Sydney Trains M set

Class of electric train operating in Sydney, Australia

The Sydney Trains M sets, also referred to as the Millennium trains, are a class of electric multiple units that operate on the Sydney Trains network. Built by EDi Rail between 2002 and 2005, the first sets initially entered service under the CityRail brand on 1 July 2002 after short delays due to electrical defects. The M sets were built as "fourth generation" trains for Sydney's suburban rail fleet, replacing the 1960s Tulloch carriages and providing extra capacity on the suburban rail network. The sets currently operate on the T2 Inner West & Leppington, T3 Bankstown, T5 Cumberland, T7 Olympic Park and T8 Airport & South lines.

Design

Vestibule

The Millennium train, like the entire Sydney Trains fleet and electric NSW TrainLink fleet, is a double decker. It is a four car consist, with the middle two cars being non-control motor cars and the two outer cars being driving control trailer cars fitted with the pantograph. The Millennium train was the first to be equipped with an AC drive system unlike the Tangara, which has a DC drive system. The sets usually operate in eight-car formations with two four-car sets combined. While the Millennium train concept is an evolution of the Tangara concept (manufactured by A Goninan & Co), the Millennium train introduced new features such as internal electronic destination indicators, automated digital voice announcements for upcoming stops, a return to reversible seating, surveillance cameras, wider stairways, a new safety yellow colour scheme, and push-button opened internal doors. The Millennium Train also introduced crumple zones to absorb impact in a collision. Interiors were designed by Transport Design International.

The train also features emergency help points, allowing passengers to contact the train crew in an emergency. The help points are located on the sides of the stairwell to the upper deck. There are actually two help points in the same location, with a large one at face height with a microphone and speaker, and a lower one with a microphone only. There are also emergency door releases which were retrofitted to the trains. These allow passengers to manually open the doors in an emergency, as recommended in the report for the Waterfall rail accident. The retrofit program was stated as having been completed in November 2014.

Like with the T, A and B sets, the M sets feature Scharfenberg couplers.

M sets are 3.03 metres (9 ft 11+1⁄4 in) wide, being classed by Transport for NSW as medium width trains, which allows them to operate within the whole Sydney Trains suburban network.

Unlike sets M2–M35, set M1 has a slightly different interior design with differently coloured doors and different seat handles for unknown reasons.

Delivery

Stairwell

The cars were constructed by EDi Rail at Cardiff Workshops. The contract included a 15-year maintenance agreement with EDi Rail to maintain the trains at a specialised maintenance centre at Eveleigh. During testing and initial revenue service, they ran as four car sets, with eight car sets commencing service towards the end of 2002 after further testing. All 35 four car sets were delivered by October 2005.

The initial order signed in October 1998 was for 81 carriages, in December 2002 an option was taken up for an additional 60. In February 2017, Sydney Trains exercised an option to extend Downer's maintenance of the trains for a further 10 years.

Criticisms

The Millennium trains were criticised for having several technical problems and causing problems with Sydney Trains, they were referred to in the media reports as The "Mi-lemon" and "Millenni-Bug" as a result. Some of the problems were caused by insufficient power supply on the overhead to cope with the power demands of the more technologically advanced trains causing them to shut down. Software bugs also contributed to the trains' poor reliability.

The Millennium trains were withdrawn from service in April 2003 while the problems were being rectified and a full audit was carried out. They were subsequently reintroduced into service in June 2003 and have since been operating on the T2 Inner West & Leppington, T3 Bankstown, T6 Carlingford, T7 Olympic Park and T8 Airport & South lines. After the new timetable was released on 26 November 2017, M sets began as 4-car services on the T5 Cumberland line on both weekdays & weekends, along with a few 8-car Waratahs.

In service

External Carriage Camera Trial

Trial cameras

In late 2008, two Millennium trains were fitted with external cameras atop of carriages near the doors, testing their use for the then-future Waratah trains. These cameras were subsequently incorporated into the final design of the Waratah train.

Lines serviced

The Millennium trains typically operate on the following lines (normally described as Sector 2):

T2 Inner West & Leppington Line: Leppington or Parramatta to City Circle via Granville

T3 Bankstown Line: Liverpool or Lidcombe to City Circle via Bankstown

T5 Cumberland Line: Leppington to Richmond

T7 Olympic Park Line: Shuttle from Lidcombe to Olympic Park on weekdays

T8 Airport & South Line: Macarthur to City Circle via Airport or Sydenham

Maintenance Depots

The trains were originally maintained at Eveleigh Maintenance Centre.

As with all other trains, these trains are not exclusively kept in Auburn overnight. They only need to return to the depot for maintenance, and at other times, they may be stabled at various yards on the lines that they operate, such as Liverpool and Leppington yards -Anastasia the train girl

Broke: electric battery cars, busses, trucks, and trains, that use volatile and unrenewable batteries that wear down and expire. Mass transit is sidelined in favor of everyone owning an EV, roads are just as awful and sprawling as ever.

Woke: Trolleys. Interurbans. Lightrail. Doodlebugs. Passenger trains. Local freight. High speed express routes. All powered by overhead catenary electric lines, fed by fast burning Thorium nuclear reactors.

Fact: at one point, a determined traveler could step onto an interurban train in Maine and travel all the way to Chicago. There is no reason, except the greed of fuel and automobile manufacturers, that this system had to be removed. And yet there is only one such system left! The South Shore is the last of these original routes left, serving from North Chicago to South Bend. There are of course commuter lines, in major cities, but these are on the decline as well, through neglect and removal of funding. We NEED to connect communities, businesses, and the very nation with rail travel again, and electric is the way to go. Just not with batteries! So easily we forget overhead electric lines.

Day 15: Pennsylvania Railroad GG1

Information from Wikipedia:

The PRR GG1 was a class of electric locomotives built for the Pennsylvania Railroad (PRR), in the northeastern United States. Between 1934 and 1943 General Electric and the PRR's Altoona Works built 139 GG1s.

The GG1 entered service with the PRR in 1935 and later ran on successor railroads Penn Central, Conrail and Amtrak. The last GG1 was retired by New Jersey Transit in 1983. Most have been scrapped, but sixteen are in museums. The GG1 was 79 feet 6 inches (24.23 m) long and weighed 475,000 pounds (215,000 kg). The frame of the locomotive was in two halves joined with a ball joint, allowing the locomotive to negotiate sharper curves. The body rested on the frame and was clad in welded steel plates. The control cabs were near the center of the locomotive on each side of the main oil-cooled transformer and oil-fired train-heating boiler. This arrangement, first used on the PRR's Modified P5 class, provided for greater crew safety in a collision and provided for bi-directional operation of the locomotive. Using Whyte notation for steam locomotives, each frame is a 4-6-0 locomotive, which in the Pennsylvania Railroad classification system is a "G". The GG1 has two such frames back to back, 4-6-0+0-6-4. The related AAR wheel arrangement classification is 2-C+C-2. This means one frame mounted upon a set of two axles unpowered (the "2") and three axles powered (the "C") hinged with the ball and socket to another frame of the same design (the +). The unpowered "2" axles are at either end of the locomotive. The GG1 was equipped with a Leslie A200 horn.

A pantograph on each end of the locomotive body was used to collect the 11,000 V, 25 Hz alternating current (AC) from the overhead catenary wires. In operation, the leading pantograph was usually kept lowered and the trailing one raised to collect current, since if the rear pantograph failed it would not strike the forward pantograph. A transformer between the two cabs stepped-down the 11,000 V to the voltages needed for the traction motors and other equipment. Twelve 385-horsepower (287 kW) GEA-627-A1 traction motors (AC commutator motors, not AC induction motors) drove the GG1's 57-inch (1,448 mm) diameter driving wheels on six axles using a quill drive. The power required was such that double traction motors were used, with two motors driving each axle. The traction motors were six-pole field, 400 volts, 25 Hz rated each at 385 hp (287 kW). The motors were frame-mounted using quill drives to the sprung driving wheels, providing a flexible suspension system across a relatively-long locomotive frame, which allowed full wheel weight to rest on the rail for good traction regardless of track condition. A series-wound commutator motor's speed is increased by increasing the applied voltage to the motor, thus increasing the current through the motor's armature, which is necessary for increasing its torque and thus increasing motor speed. The engineer's cab had a 21-position controller for applying voltage to the motors. Four unpowered leading/trailing wheels were mounted on each end of the locomotive.

In the 1930s, railroad passenger cars were heated with steam from the locomotive. The GG1 had an oil-fired steam generator to feed its train's "steam line."

Beginning in the late 1910s, the PRR received the FF1, but decided that it was too slow for passenger trains; it was relegated to heavy freight service. In the mid-1920s, it received the L5 electric, which had a third-rail power supply at the time. When the Pennsylvania built the O1 and the P5, it chose the P5 over the O1 for its ability and power on the rails. After a grade-crossing accident with the P5, the cab was moved to the center and was designated P5a. PRR still searched for the ultimate electric, since the P5 did not track well at high speeds and was wondering if the P5a could be improved even further. Soon enough, the Pennsylvania was in luck and found two contacts as early as 1932. The mechanical design of the GG1 was based largely on the EP3, which the PRR had borrowed from the New York, New Haven & Hartford Railroad to compare it to the P5a. In 1933, the PRR decided to replace its P5a locomotives; it asked General Electric and Westinghouse to design prototype locomotives with a lighter axle load and more power than the P5a, a top speed of at least 100 miles per hour (160 km/h), a streamlined body design, and a single (central) control cab. Both companies delivered their prototypes to PRR in August 1934. Westinghouse's R1 was essentially "little more than an elongated and more powerful version of the P5a" with an AAR wheel arrangement of 2-D-2. General Electric delivered its GG1. Both locomotives were tested for ten weeks in regular service between New York and Philadelphia and on a test track in Claymont, Delaware. PRR chose the GG1 because the R1's rigid wheelbase prevented it from negotiating sharp curves and some railroad switches. On November 10, 1934, the railroad ordered 57 locomotives: 14 assembled by General Electric in Erie, 18 by the PRR's own Altoona Works, and 20 more in Altoona with electrical components from Westinghouse in East Pittsburgh and chassis from the Baldwin Locomotive Works in Eddystone. An additional 81 locomotives were built at Altoona between 1937 and 1943. On January 28 1935, to mark the completion of electrification of the line from Washington, D.C., to New York City, PRR ran a special train hauled by Pennsylvania Railroad 4800 before it opened the line for revenue service on February 10. It made a round-trip from D.C. to Philadelphia; it completed the return leg in a record 1 hour and 50 minutes. In 1945, a Pennsylvania GG1 hauled the funeral train of President Franklin D. Roosevelt from Washington Union Station to New York Pennsylvania Station. In the mid-1950s, with declining demand for passenger train service, GG1s 4801–4857 were re-geared for a maximum speed of 90 miles per hour (140 km/h) and placed in freight service. They initially retained their train-heating steam generator, and were recalled to passenger service for holiday-season mail trains and 'Passenger Extras' such as those run for the annual Army–Navy football game in Philadelphia. Timetable speed limit for the GG1 was 75-80 mph until October 1967, when some were allowed 100 mph for a couple of years. When Metroliner cars were being overhauled in the late 1970s, GG1s were again allowed 100 mph for a short time when hauling Amfleet cars on trains scheduled to run 226.6 miles from New York to Washington in 3 hours and 20 to 25 minutes. On June 8, 1968, two Penn Central GG1s hauled Robert F. Kennedy's funeral train from New York Penn Station to Washington, D.C. The first designer for the GG1 project was industrial designer Donald Roscoe Dohner, who produced initial scale-styling models, although the completed prototype looked somewhat different. At some point, PRR hired famed industrial designer Raymond Loewy to "enhance the GG1's aesthetics." The final design is retrospectively 'Art Deco' as we know it today. Although it was thought until 2009 that Loewy was solely responsible for the GG1's styling, Dohner is now understood to have contributed as well. (Dohner's GG1 designs influenced the modified P5as, which debuted before the GG1 — not, as was thought, the other way around.) Loewy did claim that he recommended the use of a smooth, welded body instead of the riveted one used in the prototype. Loewy also added five gold pinstripes and a Brunswick green paint scheme. In 1952, the paint scheme was changed to Tuscan red; three years later, the pinstripes were simplified to a single stripe and large red keystones were added. On September 6 1943, the Congressional Limited crashed at Frankford Junction, in the Kensington neighborhood of Philadelphia, Pennsylvania, in the United States. The train was pulled by GG1 4930. The accident was caused by a journal box fire (a hot box) on the front of the seventh of the train's 16 cars. The journal box seized and an axle snapped, catching the underside of the truck and catapulting the car upwards. It struck a signal gantry, which peeled off its roof along the line of windows "like a can of sardines". Car #8 wrapped itself around the gantry upright in a figure U. The next six cars were scattered at odd angles over the tracks, and the last two cars remained undamaged. In total, 79 passengers died, all from cars #7 and #8, and 117 were injured, some seriously. On January 15 1953, train 173, the overnight Federal from Boston, was approaching Washington behind GG1 4876. The train passed a signal 2.1 miles (3.4 km) north of Union Station between 60 and 70 miles per hour (97 and 113 km/h), and the engineer decreased the throttle and started applying the brakes. When the engineer realized that the train was not slowing down, and applying the emergency brake had no effect, he sounded the engine's horn. A signalman, hearing the horn and noting the speed of the 4876, phoned ahead to the station master's office. 4876 negotiated several switches at speeds well over the safe limits and entered the station at around 35 to 40 miles per hour (56 to 64 km/h). The train demolished the bumping post, continued through the station master's office and into the concourse, where it fell through the floor into the station's basement. Thanks to the evacuation of the concourse, no one died, either in the station or aboard the train. A temporary floor was erected over the engine, and the hole it created, for the inauguration of President Dwight D. Eisenhower. 4876 was eventually dismantled, removed from the basement and reassembled with a new frame and superstructure in Altoona. The reconstructed 4876 survives at the B&O Railroad Museum in Baltimore. 

The accident was determined to have been caused by a closed "angle cock", a valve on the front and rear of all locomotives and rail cars used in the train's airbrake system, on the rear of the third car in the train. The handle of the angle cock had been improperly placed and had contacted the bottom of the car. Once it was closed, the air brake pipe on all the cars behind the closed valve remained at full pressure, keeping the brakes released on those cars while the brakes on the locomotive and first three cars were applied in emergency. The only major electro-mechanical breakdown of the GG1 was caused by a February 1958 blizzard that swept across the northeastern United States and put nearly half of the GG1s out of commission. Exceptionally fine snow, caused by the extreme low temperatures, passed through the traction motors' air filters and into the electrical components. When the snow melted, it short-circuited the components. On about 40 units, the air intakes were later moved to a position under the pantographs.

In 1968, the PRR, with its 119 surviving GG1s, merged with the New York Central Railroad to form Penn Central. Penn Central went bankrupt in 1970 and its freight operations were later assumed by government-controlled Conrail, which used 68 GG1s in freight service until the end of electric freight traction in 1980.

After its creation in 1971, Amtrak purchased 30 GG1s for $50,000 each and leased another 21, of which 11 were for use on New York and Long Branch commuter trains. Amtrak initially renumbered the purchased GG1s as Nos. 900 to 929; later the railroad added a prefixed "4". This replicated some of the numbers of the leased units, which were renumbered 4930 to 4939, except 4935, which kept its old PRR/PC number.

Amtrak unsuccessfully attempted to replace the GG1s in 1975 with the General Electric E60. An E60 derailed during testing at 102-mile-per-hour (164 km/h), forcing an investigation (the E60 used the same trucks as the P30CH diesel then in service with Amtrak) that delayed acceptance. The hoped-for 120 miles per hour (193 km/h) service speed was never achieved (timetable limit was 90 mph, then 80, then 90).

A replacement was finally found after Amtrak imported and tested two lightweight European locomotives: X995, an Rc4a built by ASEA of Sweden, and X996, a French design. The railroad picked the ASEA design, initially nicknamed the "Swedish swifty" or the "Mighty Mouse" and later often referred to as the "Swedish Meatball". Electro-Motive Diesel, then a part of General Motors, was licensed to build a derivative called the AEM-7. As AEM-7s arrived, Amtrak finally ended GG1 service on April 26, 1980.

The last GG1s in use were some of the 13 assigned to New Jersey Transit (#4872–4884) for its North Jersey Coast Line between New York and South Amboy (the former New York and Long Branch) that ran until October 29, 1983, thus retiring the locomotive after 49 years of service. Fifteen production locomotives and the prototype were preserved in museums. None are operational; their main transformers were removed because of the PCBs in the insulating oil.

During the mid-1930s, many railroads streamlined locomotives and passenger cars to convey a fashionable sense of speed. While the Union Pacific had the M-10000 and the Chicago, Burlington & Quincy Railroad the Zephyr, the PRR had the GG1. The GG1 has "shown up over the years in more advertisements and movie clips than any other locomotive." It was also featured in art calendars provided by PRR, which were used to "promote its reputation in the public eye." PRR-painted GG1s appear in the films Broadway Limited in 1941, The Clock in 1945, Blast of Silence in 1961, the 1962 version of The Manchurian Candidate, and Avalon in 1990. Two GG1s appear in the 1973 film The Seven-Ups—a black Penn Central locomotive and a silver, red and blue Amtrak locomotive. A Penn Central GG1 also appears in another 1973 film The Last Detail. PRR GG1 4821 appears briefly in the 1952 film The Greatest Show on Earth, hauling the Ringling Bros. Barnum & Bailey Circus into Philadelphia's Greenwich Yard, as the movie's director Cecil B. DeMille narrates the scene of its arrival. Near the end of the 1951 film Bright Victory, GG1 #4849 is shown pulling into the station. A GG1 and the Congressional were featured on a postage stamp as part of the United States Postal Service's All Aboard! 20th Century American Trains set in 1999.

The PC games Railroad Tycoon II, Railroad Tycoon 3, Sid Meier's Railroads!, Train Fever, Transport Fever and Transport Fever 2 allow players to purchase and operate GG1 locomotive engines on their train routes. The GG1 is also available with the default Trainz Simulator Games in recent years, and is available as add-ons for Railworks, Train Simulator by Dovetail Games and Microsoft Train Simulator.

Model GG1s have been produced in G, O, S, HO, N and Z scales by Rivarossi, Bachmann, Tyco, Lionel, MTH, USA Trains, Kato, Astor, Fine Art Models, Marklin and other manufacturers.

to get serious for once in my life i do actually think that battery-electric trains (and vehicles in general) do have a place in the transition to a decarbonized transportation system. i will admit though, the current obsession with battery-electric is setting a concerning precedent; that we can innovate our way out of the climate crisis instead of making concrete changes to our ways of life

the place i see battery-electric being most useful is in low-use areas, areas where installing overhead catenary is impractical, and complex interlockings/intersections where either space is limited or there’s a need to discontinue the use of a third rail for design or safety reasons

the improvement of newer technologies like ABS might prove me wrong tho idk. i will say that the absolute bare minimum though would be the electrification of mainlines

Hydrogen trains, battery trains, diesel trains, all of those are stupid ways to power a train

What we should be doing is powering trains with the magical power of 80s synth pop

A K set in its original State Rail Authority livery in the 1980s. Some sets were originally classified as R sets.

The first order featured low mounted upper deck windows, off-white and sagebrush grey interiors, and unpainted fronts. The second order featured higher mounted upper deck windows, yellow and mustard interiors and State Rail Authority candy livery fronts. The first four trailers were built as driving trailers allowing them to operate in two-car formation, although in practice they were formed into four carriage sets and often ran together as one eight-car set until 1988. These also differed in the subsequent deliveries in being fitted with air conditioning from new, rather than pressure ventilation. To provide a spare, C3550 & T4216 were also built with air conditioning. All ten carriages were fitted with different windows, being sheet glass with small opening hoppers. This was replaced with sheet glass in 1993.

To accommodate the air conditioning and associated equipment, the pantograph had to be shifted to the adjacent trailer car to which the power car is semi-permanently coupled with high voltage cables connecting the two cars. Although some power cars and trailers have been broken up and married with others during periods of heavy maintenance, many original combinations remain.

The control carriages have a flat front, with headlights at the top. They were built with four sets of marker lights, standard at the time. Different combinations of white marker lights were used to indicate different destinations. Flip-dot destination displays were installed later on, which covered the upper middle marker light. Since destination displays have been installed, marker light combinations are no longer necessary, so usually only the two upper marker lights are used. However, some trains still retain the switch for the lower marker light. The front of the train also has an emergency door for the guard compartment and windscreen wipers for the driver window only. Hoses and receptacles are provided below the windows to connect another set, since, unlike newer trains, the coupler does not carry electrical or air connections.

Like other trains of the time, the crew compartment contains a smaller compartment for the driver on the left side (in direction of travel). The guard uses the area outside of the driver's compartment, with two manual hinged doors on either side providing access to platforms. Above these doors, on the outside are blue lights indicating which compartment the guard is in.

Each vestibule has two-panel sliding doors on either side. Each door also has a vent underneath the window, which was covered when air-conditioning was installed. The doors cannot detect obstacles and continue pushing against the obstruction until it is removed or the guard reopens the doors. Small orange LEDs are located above the doors on the outside that flash when the doors are closing. They assist the guard in locating doors that haven't closed successfully. All trains were retrofitted with traction interlocking, meaning the driver cannot apply power when the doors are open.

In service

All K sets are crewed with a driver and guard. The guard uses the rear cab on a two or four-car train. On eight car trains, the guard usually uses the 5th carriage so that the entire platform can be seen. However the 4th carriage cab can also be used if there is a problem with the 5th carriage one.

All the K sets were delivered to either Hornsby or Punchbowl depots. With the trials on the ten experimental carriages judged successful, in 1986 a programme commenced to retrofit air conditioning to the second order. This saw the Beclawat windows replaced with sheet glass. It would be July 1990 before the programme was completed.

In April 1989, K sets commenced operating peak-hour services via the North Shore line to Gosford. This was extended to Wyong in January 1992. In September 1990, all Punchbowl based sets were transferred to Hornsby.

In January 1991, four sets were transferred to Flemington Maintenance Depot to operate peak-hour Illawarra line services to Port Kembla.

To replace U sets on stopping services between Gosford and Newcastle, the sets with driving trailers were re-marshaled as two-car sets from October 1996.

Following the delivery of the outer suburban Tangara sets in 1994, the K sets ceased operating the Central Coast and Illawarra services.

Upper deck after the CityDecker refurbishment of the 1990s.

During the late 1990s, all were refurbished by A Goninan & Co as part of the CityDecker program. This saw the interiors refurbished with white walls and ceilings, grey floors and blue seats. Power cars received a destination indicator and had yellow applied to the lower half of their fronts. Sliding Beclawat windows on the pressure ventilated cars were replaced with hopper windows and doors painted yellow. The first order was finally retrofitted with air conditioning just prior to the Sydney 2000 Olympics. These cars retained the hopper windows until the late 2000s, but were sealed shut with an adhesive to avoid the loss of air conditioning.

After the introduction of a new timetable in October 2009, all K sets were allocated to Hornsby to operate North Shore, Northern & Western line services, operating in 8-car formations. This was due to the noise levels inside trains when operating on the Epping to Chatswood segment. Older S sets lack sufficient sound insulation for passengers, while newer Tangara sets don't have sufficient cooling in the dynamic braking system to deal with extended shuttle runs through the tunnel.

In mid-2014, K sets are gradually transferred from Hornsby to Flemington resulting in their resumption of service on the Airport, Inner West & South, Bankstown, Carlingford and Olympic Park lines. K60 to K86 were previously running these lines, based out of Flemington Depot. Prior to 2017, K87–99 continued to run part-time on the T1 North Shore, Northern & Western lines.

In October 2013, the 2 car K Sets (K1–4) were withdrawn from NSW TrainLink Gosford to Newcastle services. The four driving trailers were converted to ordinary trailers at Hornsby and the sets returned to service on Sydney Trains services in March 2014 as K98 and K99. The existing K98 was re-numbered K91. The driver cabins in these carriages were stripped of controls however the actual walls were kept intact. The doors to the driver cabin are kept locked and the blinds are kept down. There are no passenger seats where the crew compartment used to be. Also, unlike converted S set cars, the round window on the crew compartment doors were removed and covered with a metal plate.

In July 2017, asbestos was found in the circuit breaker panels, which is inside the driver compartment of the K sets, with all withdrawn for inspection for a few weeks. All have since returned to service.

After the introduction of a new timetable in November 2017, all K sets were transferred to Sector 2.

In late 2017 and early 2018, all K sets and C sets were slightly refurbished with all poles and other safety features repainted yellow.

In 2019, set K96 was withdrawn from passenger service and had Automatic Train Protection (ATP) equipment installed. It has conducted ATP testing since then and will be retained following the retirement of the rest of the fleet for this purpose.

K sets operate on the following lines:

T2 Inner West & Leppington Line: Leppington or Parramatta to City Circle via Granville

T3 Bankstown Line: Liverpool or Lidcombe to City Circle via Bankstown

T8 Airport and South Line: Macarthur to City Circle via Airport or Sydenham

They were formerly in operation on the T6 Carlingford line until it was closed in January 2020.

Preservation

While at the moment there are no developed plans for the preservation of any K set cars, Sydney Electric Train Society has expressed interest in preserving at least one. K96 will likely be retained for the purposes of ATP testing after the K sets are withdrawn from revenue service.

Several heritage tours have used K sets prior to retirement, these have been:
