About this file

This document is Attachment A to the FY26 Army Rail Modernization Statement of Work, which provides a comprehensive inventory of locomotives distributed across 28 Army locations nationwide. The attachment lists 102 total locomotives consisting of 29 GenSet locomotives and 73 conventional/other locomotives organized by installation with their specific identifications and models.

The GenSet locomotives include models designated as 3GS21B PlateL, 3GS21B PlateC, 1GS7B, and 2GS14B, distributed primarily across major Army installations including Fort Bliss TX (5), Fort Hood TX (7), Fort Irwin CA (4), and McAlester Army Plant OK (8). The conventional locomotives comprise various General Motors EMD models ranging from 80-ton to 120-ton capacity, including GP-9, GP-10, GP-40, GP-40-2, and RP-40-2C variants, as well as one Battery-Electric locomotive at Fort Hood. The inventory spans geographic locations from Fort Lewis WA in the Pacific Northwest to Fort Eustis VA on the Atlantic Coast, including Army depots, ammunition plants, and military ocean terminals. The document notes that total quantities and locations are subject to change based on introduction of new locomotives and relocations between facilities.
