Garden Service by amtraknortheast1 Via Flickr: After NJ Transit train 3733 broke down in the North River Tunnels, Amtrak “Empire Service” GE P32ACDM 711 found its way out of the Empire State and into the Garden State. Passengers on 3733 (like myself) sat in blistering heat with no air conditioning and limited lighting for 2 hours after a pantograph on the second Arrow III married pair apparently collapsed and began arcing. After waiting for 711 to couple and the Arrow set’s brakes to release, the dead set was shoved into Secaucus Junction’s Track 3 around 9:35 PM, just over 2 hours after its originally scheduled 7:29 PM stop at the station.

Amtrak P42DCs No. 45 and 71 and P32-8BWH No. 512 glide into Glenwood Springs, Colorado with train No. 5, the Westbound California Zephyr, several minutes ahead of it's scheduled departure time of 2:43 PM. This is one of many occasions where a P32-8BWH can be seen on any Amtrak service since they're mostly used for yard switching in Los Angeles, Oakland, Chicago, and Miami these days.

The Amtrak GE P32-8BWH does very well pulling the passenger cars.

How about a nice big Pepsi?

P32 519 sits in the evening sun at Milwaukee's depot back on July 31, 1997. The GE might have had the shape of a freight diesel, but the colorful paint scheme makes her look pretty sharp. The 500's were a fixture on Amtrak's Hiawatha service back then, running between Chicago and Milwaukee.

Day 5: GE Genesis

Info from Wikipedia:

General Electric Genesis (officially trademarked GENESIS) is a series of passenger diesel locomotives produced by GE Transportation, then a subsidiary of General Electric. Between 1992 and 2001, a total of 321 units were built for Amtrak, Metro-North, and Via Rail.

The Genesis series of locomotives was designed by General Electric in response to a specification published by Amtrak and ultimately selected over a competing design presented by Electro-Motive Diesel (EMD). Until the introduction of the Siemens Charger, the Genesis series had the lowest height of any North American diesel-electric locomotives, being 14 inches (356 mm) lower than the previous-generation F40PH. This low height allows the locomotive to travel easily through low-profile tunnels in the Northeast Corridor.

The GE Genesis series is unique among recently manufactured North American passenger locomotives in that it uses a single, monocoque carbody design styled by industrial designer Cesar Vergara, thus making it lighter, more aerodynamic, and more fuel efficient than its predecessors (F40PH, F59PH, P30CH, P32-BWH). However, this makes it more costly and time-consuming to maintain and repair. In 2004, Amtrak started installing bolt-on nose cones on its units for easy replacement in the event of a grade crossing collision with a vehicle. As an example of the improvements over the predecessor locomotives, the Genesis is 22% more fuel-efficient than the F40PH while producing 25% more horsepower.  In addition, all Genesis locomotives have four-stroke engines instead of the two-stroke engines previously used in EMD counterparts.

The Genesis unit is a fully computerized locomotive which automatically controls all on-board functions, thus producing high reliability while keeping the maintenance requirements low. For example, its computers can automatically reduce the power plant's output in the event that the locomotive is overheating, or suffering from low oil pressure, low water pressure, or reduced airflow into the intakes, thus making it still operable.

All Genesis engines can provide head-end power (HEP) to the train drawn from an alternator or inverter powered by the main engine at a maximum rating of 800 kilowatts (1,100 hp), making each unit capable of providing HEP for up to 16 Superliner railcars. The P40DC and P42DC power plants can supply 60-hertz head-end power either from the HEP alternator with the engine speed-locked to 900 rpm (normal mode) or from the traction alternator with the engine speed-locked to 720 rpm (standby mode). In the latter case, traction power is unavailable. The P32AC-DM powerplant does not have to be locked at a certain rpm because it utilizes an HEP inverter, which allows the prime mover to run at 1047 rpm when providing both traction power and HEP, and to idle at 620 rpm (or notch three) while still providing HEP for lighting and air-conditioning when not providing traction power.

The trucks of Genesis locomotives were made by Krupp Verkehrstechnik, which has since been absorbed by Siemens Mobility; the trucks on the newest Genesis locomotives carry the Siemens name.

Three models of Genesis were built by General Electric, the P40DC, P42DC, and P32AC-DM.

The P40DC (GENESIS Series I) or Dash 8-40BP (originally known as the AMD-103 or Amtrak Monocoque Diesel - 103MPH) is the first model in the Genesis series, built in 1993. The locomotive operates in a diesel-electric configuration that uses DC to power the traction motors, producing 4,000 horsepower (2,980 kW) output at 1047 rpm. Power output to the traction motors is 3,550 hp (2,650 kW) when running in HEP mode (900 rpm) with a 0 kW HEP load. Traction horsepower in HEP mode decreases to a bare minimum of 2,525 horsepower (1,880 kW) when providing the maximum 800 kW (1,100 hp) HEP load to the train. The P40DC is geared for a maximum speed of 103 miles per hour (166 km/h). The P40DC was succeeded in 1996 by the P42DC.

A feature unique to the P40DC and P32AC-DM is a hostler stand at the rear of the locomotive providing increased visibility and reversing capabilities to the engineer while conducting reverse operations. When a unit is in operation from this stand it is limited to 10 mph (16 km/h) and a dead man's switch protects against movement without an operator being present. Another unique feature to the original P40DC were the two strobes above the cab and an emergency flasher between the strobes. When they were overhauled, those features were removed.

Both the P40DC and P42DC allowed Amtrak to operate heavy long-distance trains with fewer locomotives compared to the older EMD F40PH locomotives; two P40DCs could do the same work as three F40PHs. Additional deliveries of the P42DC ended up replacing the P40DCs. Three units were wrecked (819 in the 1993 Big Bayou Canot train wreck and 807 and 829 in the 1999 Bourbonnais, Illinois, train crash) and scrapped. Eight were leased and later sold to the Connecticut DOT for Shore Line East in 2005, and four were rebuilt and sold to New Jersey Transit in 2007; NJ Transit sold their units to ConnDOT in 2015. The remaining 29 units were placed out-of-service for many years. 15 of these units have been rebuilt using 2009 ARRA stimulus funds and returned to service, now in the Phase V livery, except for 822, which is painted in Phase III Heritage livery for Amtrak's 40th Anniversary. The units that were not rebuilt or sold have since been disposed.

In January 2018, ConnDOT awarded a contract to Amtrak to overhaul their twelve P40DC locomotives at the Beech Grove Shops. The first unit was completed in early 2021.

By 2007, New Jersey Transit had upgraded their P40DC units with updated prime movers to match the 4,250 horsepower (3,170 kW) of the successor P42DC. This was done by readjusting the position of the lay shafts within the prime mover. Amtrak has returned 15 of their P40DC units to service as part of a project funded through the American Recovery and Reinvestment Act of 2009.

The first of the units were returned to service in March 2010 after being overhauled at the Beech Grove Shops. They were upgraded like NJT's units had been a few years before to have 4,250 hp (3,170 kW) and match the P42DC's maximum speed of 110 mph (177 km/h). They also received updated cab signaling systems. The upgraded locomotives still have mechanical air brakes, which makes them most suitable for trains that only require a single locomotive. This differs from the electronic air brakes on the P42DC and P32AC-DM. They also feature a builder's plate indicating that they were rebuilt under the auspices of the TIGER stimulus program.

The P42DC (GENESIS Series I) is the successor model to the P40DC. It has an engine output of 4,250 horsepower (3,170 kW) at 1047 rpm, or 3,550 horsepower (2,650 kW) when running in HEP mode (900 rpm) with a 0 kW HEP load. Traction horsepower in HEP mode decreases to a bare minimum of 2,525 horsepower (1,880 kW) when providing the full 800 kW HEP load to the train.

The P42DC has a maximum speed of 110 mph (177 km/h). Tractive effort is rated at 280.25 kN (63,000 lbf) of starting effort and 169 kN (38,000 lbf) of continuous effort at 38 mph (61.2 km/h) given wheel horsepower of 3,850 horsepower (2,870 kW). P42DCs are used primarily on most of Amtrak's long-haul and higher-speed rail service outside the Northeast and lower Empire Corridors. They will be replaced on long-distance service by 125 Siemens ALC-42 Charger locomotives between 2021 and 2024, but will remain in service on corridor trains.

Via Rail Canada has utilized P42DC locomotives since 2001, when they replaced the LRC locomotives in 2001. They are currently on services with speeds up to 100 mph (161 km/h), mainly on the Quebec City-Windsor rail corridor.

The P32AC-DM (GENESIS Series II, short for "Passenger, 3,200 hp (2,400 kW), Alternating Current, Dual Mode")  was developed for both Amtrak and Metro-North. They can operate on power generated either by the on-board diesel prime mover or power collected from a third rail electrification system at 750 volts direct current; the third-rail shoes are used on the over-running third-rail into Penn Station for Amtrak units and the under-running third-rail into Grand Central Terminal for Metro-North. The P32AC-DM is rated at 3,200 horsepower (2,390 kW), 2,900 horsepower (2,160 kW) when supplying HEP, and is geared for a maximum speed of 110 mph (177 km/h). Tractive effort is rated at 275.8 kN (62,000 lbf) of starting effort from 0 mph (0.00 km/h) to 14 mph (22.5 km/h) and 113.43 kN (25,500 lbf) of continuous effort at 40 mph (64.4 km/h) given wheel horsepower of 2,700 horsepower (2,010 kW).

The P32AC-DM is unique as it is equipped with GE's GEB15 AC (alternating current) traction motors, rather than DC (direct current) motors as used in the other subtypes. It is also only one of two modern American electro-diesel locomotives with third-rail capability, along with the EMD DM30AC operated by the Long Island Rail Road. NJ Transit and Exo's Bombardier ALP-45DP electro-diesel locomotive can operate from overhead catenary electrification.

The P32AC-DM is only used on services operating north from New York City, where diesel emissions through its two fully enclosed main terminal stations are prohibited. Amtrak rosters 18 P32AC-DM locomotives and uses them for its Empire Service, Ethan Allen Express, Lake Shore Limited (New York section), Adirondack, and Maple Leaf services, all which travel to New York Penn Station. Metro-North rosters 31 P32AC-DM locomotives on push-pull trains to Grand Central Terminal; four are owned by the Connecticut Department of Transportation.

In December 2020, the Metropolitan Transportation Authority of New York board approved a Federal Transit Administration-funded $335 million contract for 27 dual-mode locomotives, based on the Siemens Charger design. The new dual mode locomotives will replace the 27 existing P32AC-DM locomotives used on Metro-North's Hudson Line, Harlem Line, and Danbury Branch; they will use third rail electric power to enter Grand Central Terminal. The order includes additional options for up to 144 more locomotives, which includes 32 additional for use by Metro-North, 20 for the New York State Department of Transportation (for Amtrak Empire Service trains), and 20 for the Connecticut Department of Transportation.

During the middle of the day, Salt Lake City's Amtrak station at the Rio Grande depot was a great place to observe passenger train power laying over from the Desert Wind and Pioneer trains. Three of Amtrak's contemporaries were on hand on May 28, 1994, a GE P40DC (GENESIS AMD-103), a GE P32-BWH, and an EMD F40PH. On May 10, 1997 the Pioneer and Desert Wind trains were discontinued and by 1999, the Amtrak depot was closed and the tracks were dismantled from the depot property to make way for a shopping mall.
