AI Contract Overview

The U.S. Army Transportation Command, in partnership with the Army Contracting Command-Detroit Arsenal, is seeking industry input to replace the aging DODX 40000-Series heavy-duty flatcars that will be retired starting in 2031 due to age constraints. These railcars currently transport two 72-ton M1A2 SEPv3 Abrams tanks or equivalent heavy tracked vehicles on a single deck and must be replaced with modern designs that maintain or exceed this capacity while accommodating potential future vehicle weight growth. Four specific design concepts are under consideration: a modernized version of the existing DODX 40000-series capable of carrying two tanks on one deck; a modernized DODX 41000-series designed for one tank per deck; a dual-unit flatcar configuration with two car bodies permanently connected by a draw bar; and an open-design concept for any innovative solution not previously considered that meets all requirements. The initiative is structured as a Commercial Solutions Opening to foster competition and innovation, with responses used solely for market research and planning, not to form binding contracts. All submissions must comply with AAR Plate B clearance standards, safely negotiate a minimum 180-foot radius curve, incorporate AAR-approved hydraulic cushioning with active draft protection, and support circus-style loading via stationary end ramps with a gap no greater than five feet between units, ideally four feet. Deck dimensions must be at least 10 feet 5 inches wide, with 10 feet 8 inches preferred, and a height between 48 and 51 inches above the rail. The design must include four flush-mounted steel anchoring channels along the length and two additional edge channels, as well as collapsible ISO pedestal mounts for three TEU containers with no more than a four-inch gap between them. Railcars must use standard commercial components and be production-ready for rapid implementation. Response proposals must include company size, AAR M-1003 Certification for Activity Code A20, and Rough Order of Magnitude unit pricing broken into four production tiers based on annual volumes from 1–50, 51–100, 101–200, and over 200 railcars, with pricing including sixteen 1/2-inch tiedown chains per loaded tank. The total anticipated production volume is approximately 500 railcars, potentially expanding to 1,200 depending on future needs, with a minimum required production capability of 1

Full Description

This initiative is focused on replacing the Army's existing Defense Freight Railway Interchange Fleet (DFRIF) heavy-duty flatcars which are facing mandatory age-driven retirement starting in 2031. These heavy-duty flatcars, known as the “DODX 40000-Series”, currently can carry two 72-ton M1A2 SEPv3 Abrams Main Battle Tanks and other similar Heavy Tracked Vehicles (HTVs) on a single deck. The U.S. Army Transportation Command (ARTRANS) is seeking commercial railroad flatcar design and production services to procure replacement heavy duty flatcars capable of carrying up to two nominally 72-ton M1 tanks or equivalent HTVs. This railcar design should also be capable of carrying all other applicable military equipment and containers with maximized carrying capacity (allowed by design) to accommodate potential vehicle weight growth. ARTRANS in conjuction with Army Contracting Command- Detroit Arsenal (ACC-DTA) is requesting information to engage relevant railcar builders on the availability and feasibility of requested design concepts which ARTRANS has identified as low risk and potentially capable of meeting necessary requirements. Additionally, ARTRANS seeks feedback from industry on other applicable design concepts that may meet the stated requirements but have not been previously considered. ARTRANS is seeking information to foster a robust and competitive future Commercial Solution Opening.

ARTRANS is seeking information on different general railcar design concepts which have significant design and/or capability differences. These concepts were assessed as feasible and at a low risk for rapid production and implementation into interchange service. These concepts include:

Modernized DODX 40000-series design concept to carry two heavy tracked vehicles on a single deck.
Modernized DODX 41000-series design concept to carry one heavy tracked vehicle on a single deck.
Two flatcar bodies permanently connected by a draw bar capable of carrying one heavy tracked vehicle per deck.
An “Open Design” for previously unconsidered design concepts which can carry two 72-ton M1 tanks and meet all other ARTRANS requirements.

This Request for Information (RFI) formally opens on 06 May 2026. All responses must be submitted no later than 17:00 EST on 26 June 2026. Information received after this closing date and time may not be reviewed or considered for subsequent phases of this initiative.
