The program, which began inis the latest for the railroad to upgrade older and less reliable locomotives in its fleet. The rebuild program features a complete electrical upgrade, replacing the existing Siemens electrical equipment, including the inverters, with Mitsubishi electronics. The existing cab is replaced with a new isolated SD70ACe cab along with a number of other smaller changes to the locomotive during rebuild.

Trains 21 Contributors Mike's Collection.The Union Pacific has currently put in the largest purchase order for these units, and as a display of respect for the railroads it has incorporated, has produced six "Heritage" style painted locomotives with road numbers designated by the year they were merged into the UP.

This model is equipped with direct current DC traction motorswhich simplifies the locomotive's electrical system by obviating the need for computer-controlled inverters as are required for alternating current AC power. Other than the CR paint scheme these units were built to NS specifications and numbered - in series with Norfolk Southern's already purchased SD70s. The SD70M has a wide nose and a large comfort cab officially known as the "North American Safety Cab"allowing crew members to ride more comfortably inside of the locomotive than the older standard cab designs.

The Phase 2 cab has a two-piece windscreen like the Phase 1 windscreen but the design of the nose is more boxy, with a taller square midsection for more headroom. Split-cooling is a feature that separates the coolant circuit for the prime mover and the circuit for the air pumps and turbocharger. There are two versions of this radiator: the older version has two large radiator panels on each side, and the newer version has four square panels on each side.

An order of SD70Ms made history when Union Pacific ordered units of the model UP through UPinclusive, although was renumbered to accommodate steam locomotive Big Boy in [4]. This order was later extended by nearly additional units UP and below, UP and above, except forwhich was left vacant for the Union Pacific Challenger The SD70I is a version of the SD70M which has been fitted with a cab that is isolated from the frame of the locomotive with rubber gaskets officially known as a "WhisperCab".

The isolation reduces noise and vibration from the prime mover. A seam is visible across the nose and on the long hood where the cab connects with the body. The Alaska Railroad ordered their locomotives with head-end power to make them suitable for both freight and passenger service; no other railroad ordered this variant. These units, unlike previous SD70ACe's, have one inverter per axle on the trucks, rather than EMD's traditional one inverter per truck design.

Production began in The results of this setup are higher power throughout a broader RPM range, better fuel efficiency, and lower emissions.

An EGR system is applied as well, allowing the engine to achieve Tier 4 without the use of urea aftertreatment. Another new feature of this engine is the Double-Walled Fuel Injection System that increases safety and provides simplified maintenance works.

The units are also equipped with "radial bogies" which offer increased adhesion and better ride quality. While it retains the basic SD70 designation, the locomotive has several major new features that set it apart from its successful ancestor such as a vibration-isolated powertrain, and alternator start capability.

The LCi in the model designation stands for Low Clearance international as these locomotives are designed to negotiate the tight clearances under the mine equipment. The first member of the class was purchased for parts and dismantled upon arrival in Australia.

This was because it was cheaper to purchase a complete locomotive than buy the components individually. Construction was sufficiently advanced when the deal was concluded for them to have been painted, hence they were delivered in BNSF orange livery. Some modifications have been made to bring them in line with the rest of the fleet. An additional 18 units numbers were delivered in the second half ofbringing the total of SD70ACe type locomotives in service to In July fellow Pilbara operator, Fortescue Metals Grouptook the delivery of the first of a fleet of 19, later extended to 21 The first 25 units were ordered for Saudi Railway Company in April and assembled in the London, Ontario plant for delivery in the second half of Special features include a pulse filtration system, movable sand plows, EM control system and FIRE display system.

The new IAC system improves the existing traction system. The first of these have since been released. The initial order was for 30 units and then increased to Canadian Pacific originally rostered 61 SD90MACs, These units spent much of the decade parked in long term storage, with the exception of three, which were retired and scrapped in The remainder will receive the standard CP red paint scheme.

The SD70ACC has been rebuilt with AC traction motors, an AAR-style control stand, an electrical cabinet with Mitsubishi electronics, a new main alternator, and additional weight to increase the maximum weight topounds. As of January52 units have been rebuilt and have since been released to service, with many more units undergoing rebuild.Click here to see what you are missing! Very Nice indead, Question, Are the Crews happy with them and are they running great, as no break downs etc??

Did they change any of the radiators at all and any other part of the roof line in the make over?? Cheers Brian in New Zealand. All I've heard out of CP Corporate is that they are performing very well and a new order may be incoming, though I'm not sure how many frames are left to build off of so it might be SD70ACC's instead.

There are so many SD70 frames available now that they may institute a larger upgrade program for them - the CN order is underway too I believe. The only major change in terms of roof line is the cabs from what I know, though the internals mayhave had more changes such as the radiators without any telltale external signs.

Nice work on the photos. Clean locos look great. Thanks for that update - I hadn't heard that about the ACC's. Author: perklocal Nice Set!

Very Fresh.

Author: Train Nice work on the photos.Although the original SD70 Series line; including the subsequent SD70ACe, were initially expected to end domestic production by as a result of the engine line and subsequent engine model G3C-T3 having failed to meet Tier 4 emissions regulations, the new EMD J-equipped SD70ACe-T4 prototype was unveiled during the Railway Interchange rail expo in the twin cities region of Minnesota, and furthermore rebounded the line and subsequent locomotive model.

But as ofthe Tier 3-compliant model is available for export only, while specialty variants such as the SD70ACe-BB are currently in production. As ofTier 4 Credit T4C locomotives are available for purchase specifically for Class 1 railroads that have earned credits toward purchasing new Tier 4-compliant locomotives.

As ofthe SD70ACe is still currently in production, though the main model is available for foreign export only, for it fails to meet Tier 4 requirements and regulations implemented by the EPA; despite having been Tier 3-certified several years prior in Said units are equipped with distinct panels mounted between the railing of the frame and air intake section, and are meant for tunnel operations drawing cool air more effectively into the air intakes and blocking dust and other particles from entering.

The newly-manufactured Tier 3-compliant diesel locomotives are further prohibited for operating within American borders or on US soil, yet rebuilds or remanufactured locomotives meeting Tier 3 requirements are exceptional for domestic use.

In other words, the SD70ACe was the first domestic model to be assembled internationally for domestic-based customers; although models like the SD60GP60and so-forth were primarily assembled in London, Ontario between CEECOamong various other facilities scattered across the continent as a result of limited shop capacity at London.

Though, the diesel's have slightly larger cabs to provide better insulation, weight distribution, and crew safety similar to the various GEVO " C45AH " units produced from GE that were delivered during the same time.

EMD SD70ACe-T4

The name of the locomotive type or model itself, is meant to designate the series SD70 and tractive power AC. Said models like the SD40X share a similar dilemma. BetweenUnion Pacific painted six SD70ACe units into heritage schemes honoring the respective mergers with each railroad they acquired.

In celebration of the railroad's 30th anniversary, Norfolk Southern painted 10 SD70ACe units into the fallen flag railroad schemes that make up the company's heritage. An additional 10 ES44AC units were also painted to accompany them. Sometime between andBNSF experimented with LNG liquified natural gas for testing and evaluation purposes as an alternative to diesel fuel similar to the BN's light natural gas tests from the s.

The EMD SD80ACe, a similar type of diesel locomotive utilizes a similar design and is practically an upgraded, V20 5,hp version of the SD70ACe, yet it ironically isn't due to being a specialty locomotive, but with a similar appearance. Such as having radiator "fins" or "wings", a large radiator cabinet placed on one side, and air tanks placed on another.

Although they originally proposed on receiving 10 units, they received only 3 ex EMDX Earlier KCS Kansas City Southern SD70ACe units owned by the railroad were painted in the railroad's generic grey with yellow stripes scheme, and were some of the last locomotives on the railroad's roster to be painted in such scheme before the classic or vintage-esque "Belle" scheme was eventually developed later units were also some of the first to actually receive the "Belle" scheme on their roster as well; ironically.

Many SD70ACe and SD70M-2 units built prior to still feature now out-dated and no longer supported Windows XP and Vista operating systems for displaying stats on the desktop monitors, while later units utilize Windows 7.

Fortunately, 72 was salvageable, and is currently back in service, while nos.The first locomotive entered the rebuilding process in Septemberwhich was number As ofall units have been released into active service. The Siemens electronics will be replaced with Mitsubishi electronics. The trucks will be rebuilt only as needed and they are not getting traction motors swapped out. EMD's upgrade program, however, was never carried out due to unresolved reliability issues with the EMD was responsible for delivering the locomotives, and all units have been delivered as of November They are numbered — They will be numbered — While owned by Union Pacific, the units started developing cracks in the frames around the fuel tank mounts.

UP worked with EMD to solve the frame cracking problem by adding additional mounting brackets between the frame and fuel tank. In addition, the fuel filler pipes were modified to only allow a maximum of 4, gallons of fuel to be added. After being rebuilt in the SD70ACU program, the maximum weight initially increased topounds due to the additional weight of the new widenose and cab. Starting with the 35th SD70ACU rebuild, NS began adding additional weight to each end of the units to increase the maximum weight topounds.

The first 34 units will also have the additional weight added as shop time permits. Those units that have received the additional weight are,,,,,and They retain their original TA22 main alternator and 1TB traction motors.

A new electric parking brake has been added with brake wheel on the left side of the long hood. Ditch lights have also been added to the rear during rebuilding.

It also distinctively sports invasion stripes on the rear hood similar to those applied to Allied aircraft prior to the D-Day landings. All five commemorative military units feature Canadian Pacific's unique Support Our Troops logo, as well a Canadian and American flag on opposite sides of the locomotive.
