TUNNEL #29

Looking at some random downloads, realized a common theme was that Tunnel #29 is The. Cutest. Tunnel.

The 2% grade from Denver up to the Moffat Tunnel crawls through South Bend Canyon (along South Bend Creek) with superfluous tunnels and a surfeit of sharp curves, thanks to the mandate of then-Chief Engineer H.A. Sumneso who surveyed the Moffat Route's well-nicknamed "tunnel district" at bountiful π/1 ratio of rail to "as the crow flies" distance as he tried every trick not to make it steeper than 2%

A blasted rock bore barely 78 feet in length, tight-clearance Tunnel 29 on the Moffat Route is at milepost 36.38 and sandwiched between one of Sumneso's super-tight 12° cruves and the "curved bridge with no name" over South Bend Creek (which is officially named "Bridge 36.45" after it's milepost location) The feature on the creek's right bank seems to be locally nicknamed the Gibraltar Cliffs, from whence railfans look down on the tiny trains below.

The cutest tunnel? Yep. Did I mention the Ski Train?

Union Pacific’s Big Boy Locomotive - World’s Largest and Most Powerful Train

If Jay says 4014 is the A.) "largest steamer in the world" B.) "world's largest train" C.) "world's most powerful train" &etc ...then the lies must be true, right?

There are many locomotives in the world; 4014 is impressive in all regards... But the superlatives have gotten ridiculous and wildly inaccurate —but their SEO is great so they don't even bother asterisking their claims. Feels like I'm being marketed to by a cult #UP4014

THE CANCER GAMES:

May the odds be forever in your favor!

But  your odds of surviving drop significantly  if:

>You live in Radioactive City, Pocatello Idaho,

>You eat food produced with Radioactive Fertilizers (Radioactive Foods).

>You live anywhere in Southeastern Idaho’s 140,000 square miles of Phosphate/Uranium fields.

>You drink waters from any stream or water source contaminated by processed uranium materials stored all across the western USA on the UPRR (Union Pacific Rail Road) that leaches into every water crossing.

Enjoy all the fine food we provide for you.

Florida is now the major producer of Radioactive Fertilizers in the USA. Idaho is scared they will go to jail for killing and destroying millions of people and children’s lives.

Six Trains in One Hour on Cajon Pass - November 2024

Day 20: GE Evolution Series

Info from Wikipedia:

The Evolution Series is a line of diesel locomotives built by GE Transportation Systems (now owned by Wabtec), initially designed to meet the U.S. EPA's Tier 2 locomotive emissions standards that took effect in 2005. The first pre-production units were built in 2003. Evolution Series locomotives are equipped with either AC or DC traction motors, depending on the customer's preference. All are powered by the GE GEVO engine.[4]

The Evolution Series was named as one of the "10 Locomotives That Changed Railroading" by Trains Magazine and was the only locomotive introduced after 1972 to be included in that list.[5]

The Evolution Series locomotives are some of the best-selling and most successful freight locomotives in United States history.

Currently, six different Evolution Series models have been produced for the North American market. They are all six axle locomotives and have the wheel arrangement C-C (AAR classification) or Co′Co′ (UIC classification), except for the ES44C4 which has an A1A-A1A wheel arrangement and the meter-gauge version developed for the Brazilian network ES43BBi which is B-B-B-B.

The ES44DC (Evolution Series, 4,400 hp, DC traction) replaced the Dash 9-44CW model in the General Electric catalogue. Primary users are BNSF Railway, CSX Transportation, and Canadian National Railway. Pilbara Iron in Australia ordered a lengthened, international version designated ES44DCi. The extra length is used for a larger radiator to increase cooling capacity in the Australian outback.

The ES44AC (Evolution Series, 4,400 hp, AC traction) replaced the AC4400CW model in the General Electric catalogue. These locomotives have been ordered by every Class I railroad in North America: Union Pacific Railroad (who refers to these locomotives as the C45ACCTE), BNSF Railway, CSX Transportation, Norfolk Southern Railway, Kansas City Southern Railway, Kansas City Southern de Mexico, Ferromex, Canadian Pacific Railway, and Canadian National Railway.

The ES44C4 (Evolution Series, 4,400 hp, C to denote 3 axles per truck, 4 traction motors) was introduced in 2009. While similar to the ES44AC, the ES44C4 has two traction motors per truck, instead of the conventional three such as on the ES44AC. No ES44C4s with DC traction were built. The center axle of each truck is unpowered, giving an A1A-A1A wheel arrangement. BNSF Railway is the launch customer for this model, ordering an initial batch of 25 units numbered 6600–6624.

The ES44C4 was initially only built for BNSF. The 4200s and units 7921-7999 are certified as Tier 4 Credit units, while the others are Tier 2 or Tier 3. On 30 January 2014 Florida East Coast Railway announced that they would buy 24 ES44C4s, to be numbered 800–823, for heavy haul service and intermodal traffic. All were delivered by the end of 2014, in order to beat the EPA's deadline on exhaust-emissions standards for new-built Tier 3 locomotives.

A feature of these units is a variable traction control system in their computer systems. One of the differences between an ES44AC and an ES44C4 are the air cylinders and linkages on the truck sideframes of the ES44C4; these are part of the traction control system. Every time a variation in grade, traction, or wheel slip occurs, the computer adjusts the pressure in these cylinders to maintain sufficient adhesion, by varying the weight on the drive axles.

The ES44DCi (Evolution Series, 4400 horsepower, DC traction, international version) was built for the Rio Tinto railway in Australia. The ES44ACi was built for the Roy Hill and Rio Tinto Group.

Rio Tinto's units can be remotely driven, meaning nobody has to be in the cab as they can be controlled from a control center.

The ES44ACi/DCi is essentially an ES44AC/DC in a GE AC6000CW's body, with the radiator at the end protruding out over the rear deck in the same way the AC6000CW does. The locomotive's large radiator allows it to handle the Australian outback's extreme temperatures.

Roy Hill has ordered 21 ES44ACi locomotives, and is currently in possession of all 21 locomotives (numbered 1001 "Ginny"-1021). Rio Tinto ordered 100 ES44DCi locomotives and has all 100 (numbered 8100–8199) and 21 ES44ACi locomotives (numbered 9100–9120) and more are on order.

Ferromex also acquired 50 ES44ACi. As the construction of these locomotives was subsequent to the new environmental laws of the US, GE cataloged them only as ES44ACi, although in the external technical specifications of the locomotives say ES44AC). These locomotives can no longer reenter the US operating.

The ET44AC (Evolution Series Tier 4, 4,400 hp, AC traction) replaces the ES44AC model. These locomotives have been ordered by most of the Class I railroads in North America, including Union Pacific, CSX Transportation, Norfolk Southern and Canadian National Railway. BNSF Railway will be receiving similar ET44C4 locomotives, which have no traction motor on the middle axle of each truck. CSX designates their ET44ACs as ET44AH, due to their locomotives being heavy-ballasted.

The TE33A is an export 1520 mm gauge locomotive in the GE Evolution Series.

The Evolution Series locomotives are visually similar to the AC4400CW, although small differences are evident. The most noticeable difference is the radiator section at the rear of the locomotive is larger to accommodate the GEVO's Air to air intercoolers. As with the AC6000CW, the radiators project beyond the end of the hood. On the ES44ACi and ES44DCi models, the radiator extends in the same way as the AC6000CW, protruding out over the rear deck. For the other Evolution Series locomotives, the radiator does not protrude completely over the rear deck, but rather sits nearly flush with the rear of the engine hood. Unlike previous GE locomotives, the grills under the radiator are at two different angles. The increase in radiator size is due to the necessity for greater cooling capacity in the locomotive in order to reduce emissions. The other major difference between the Evolution Series and earlier models are the vents below the radiators, which are larger than those on previous GE locomotives.[11] Also, all Evolution Series units have air conditioners mounted below the cab on the conductor's side.

In 2002, GE and UGL Limited launched the Evolution Series locomotive, and in 2009, continued their partnership for another 10 years for UGL to distribute and sell GE locomotives in Australia.

Transnet Engineering in South Africa has a license to manufacture 233 4,200 hp (3,100 kW) 3 ft 6 in (1,067 mm) Cape gauge ES40ACi locomotives for Transnet Freight Rail, with core components including GEVO-12 engines supplied from the United States.

The first six of these Class 44-000 locomotives were built in Erie, Pennsylvania in April and July 2015. In October 2015, the first of the 227 South African-built locomotives was nearing completion at Transnet Engineering's Koedoespoort shops in Pretoria.

Built in 1910 before automobiles were a prevalent form of transportation, the Newcastle Arch under the Union Pacific Railroad Tracks was constructed to allow wagons and such passage under the railroad without impacting rail travel which at the time was the major mode of transportation across the USA. Newcastle is a small community in Placer County California basically developed around the Union Pacific Railroad in the foothills of the Sierra Nevada range at about 936 feet above sea level. The stone faced 82 foot length concrete tunnel only has the girth to allow one vehicle to pass through so it has stop signs at both ends and you have to stop and survey before proceeding. I’ve seen several of these single vehicle underpasses in Northern California which is logical because the railways need to adjust to the increasing altitude in the terrain and it affords the opportunity for such passageways beneath railways. The road which passes through the arch is old California Highway 40 and as such is referred to Old State Highway. - [ ] #developportdev @gothamtomato @developphotonewsletter @omsystem.cameras #excellent_america #omsystem @bheventspace @bhphoto @adorama @tamracphoto @tiffencompany #usaprimeshot #microfourthirds #omd #m43photography @visitcalifornia @placercounty @uprr (at Newcastle, California) https://www.instagram.com/p/ClmlT95vS-3/?igshid=NGJjMDIxMWI=

Also, because I’m physically incapable of talking about things without also talking about politics:

The Steel Bridge is owned by the Union Pacific Railroad, but carries a public street, all of the light rail lines, and a goodly chunk of buses over its span. It’s also 120 years old and in such a state of disrepair that the auto lanes now have a weight limit of 10 tons, and I’m pretty convinced that it’s not going to be replaced until it collapses, because doing so would require the UPRR to shut it down for probably a couple of years, and god forbid they do that.

what would you consider to be the prettiest bridge you’ve seen? be it in person or an image.

Oh that’s kind of a big question innit.

I mean I live in Portland, and we have a ton of bridges here, so probably one of those. It’s kind of a three way split tbh between the St. Johns Bridge

The Hawthorne Bridge

and now, the final (former, sadly.) member of up's steam giants!

when 3985 first arrived on the Union Pacific, they were actually pretty chipper and quite the optimistic Guider. but after the events of Dieselization and being out of service for a while which then led to their eventual retirement. over that period of time, they became more quiet and reclusive. not to mention they've drifted from their only sibling (3977) quite a bit. despite all this, they got by with Legend and the other Heritage Guiders' support. although they're... not as cheerful or optimistic nowadays, they're still seen as one of Union Pacific's legendary steam Guiders.

questions about ratw are always appreciated!!
