List of USRA diesel locomotive types (Kaiserreich: Legacy of the Weltkrieg)

As of 2022, the bulk of the United States Railway Administration locomotive fleet is diesel.
== List of USRA diesel locomotives ==
=== Pre-Nationalization Designs ===
Many pre-nationalization designs continued production after January 1, 1947, mainly orders that were made by companies before then.
==== EMD Models ====
EMD was the most-numerous of the pre-nationalization diesel models. At least two models survive to the present day.

==== ALCO models ====
ALCO models were the second-most numerous of the pre-nationalization designs. Several FAs survived in Long Island Rail Road service until 2000, while a single S-2 is still used by Amtrak as a shop switcher.

==== General Electric models ====
While many pre-nationalization GE models passed into USRA ownership, the USRA divested itself of these locomotives to railroads that remained in private ownership. GE is considered one of the "standard" locomotive builders.

==== ALCO models ====
After ALCO went out of business in 1969, all ALCO locomotives were deemed "non-standard", and the USRA set a deadline of December 31, 1982 for all sheds to withdraw all ALCO locomotives; the sole exception was the RS-3m, which had been rebuilt with an EMD engine.

==== Fairbanks-Morse models ====
FM locomotives developed a nasty reputation of constantly leaking oil, making them unpopular with both road and maintenance crews. The USRA deemed all FM models "non-standard" in 1975, and set a deadline of December 31, 1978 for all sheds to withdraw the locomotives.

==== Baldwin models ====
Baldwin locomotives were a mixed bag, as many were built differently from each other, blamed on backroom dealings with locomotive shedmasters who wanted personalized locomotives as "vanity objects". Many, however, were also rugged and reliable, and were very powerful. After Baldwin exited the diesel market, they continued building USRA Standard steam locomotives until procurement ended in 1964. In 1974, all Baldwin diesels were deemed "non-standard", and the USRA set a deadline of December 31, 1976 to withdraw all Baldwin locomotives; a single pre-nationalization VO-1000 that had been re-engined by EMD in 1970 remained in service at the ex-ATSF sheds in Kansas City and Topeka until 2009, and is now preserved.

==== Lima-Hamilton models ====
To this day, railfans are still debating what possessed the USRA to purchase Lima-Hamilton locomotives. Every model produced by the company was an unmitigated disaster, with constant breakdowns and complex mechanical workings that reportedly made some maintenance workers cry, resulting in the USRA abruptly declaring all of them "non-standard" on December 15, 1965, and giving a strict deadline of December 31 of that year to withdraw all Lima-Hamilton locomotives. As a result, no L-H locomotives made it to the 1971 sectorization. The USRA was all too eager to scrap them, viewing them as an embarrassment, but several were snapped up by private railroads. Lima-Hamilton locomotives have fared poorly in preservation, with a single LS-750 and two LS-1200s preserved; the sole LS-750 is operational.

==== MK Rail/MotivePower, Inc. models ====
MK Rail, a subsidiary of Morrison-Knudsen, built several models of locomotives for the USRA in the 1990s, chiefly updated variants of the venerable EMD F40PH. MK Rail also attempted to build a six-axle freight locomotive, the MK5000C, but only six demonstrator units were produced before the high horsepower locomotive program was discontinued; all are still in service. MK Rail's successor, MotivePower, Inc., exploded onto the scene in 2003 with its MPXpress line of locomotives that quickly became a staple of commuter trains. MPI has also built several models of freight diesels, and repowered existing locomotives, all with their own low-emission engine design.

==== Brookville Equipment models ====
Mainly a manufacturer of streetcars and light industrial locomotives, the USRA gave Brookville its big break in 2008 when it ordered 12 locomotives for Metro-North. Since then, Brookville has built several models of locomotives for both the USRA and its associated sectors, as well as private sector railroads such as the Central California Traction Company.

==== Siemens Mobility models ====
At one time, a German company building locomotives for the USRA was considered unthinkable, as the United States and Germany were bitter enemies in the Kalterkrieg. This changed in 2010 when the USRA ordered 70 electric locomotives for Amtrak. Siemens' line of Charger diesel locomotives are a highly-adaptable design that can be used for commuter, corridor, express, and higher-speed services; to this end, the USRA plans to replace large portions of its passenger locomotive fleet with Chargers, displacing the GE Genesis locomotives.

==== Aftermarket rebuilds ====
The USRA frequently rebuilds older locomotives to extend the working lives of locomotives that would otherwise be scrapped, as the USRA has a policy of "waste not, want not".
