Central Gulf Railcar Services, LLC

Central Gulf Railcar Services, LLC, doing business as FSI Railcar Service Center, is a foreign-owned for-profit limited liability company based in Mobile, Alabama that provides freight railcar repair, maintenance, and comprehensive logistics support to the U.S. Army as a prime contractor exclusively under full-and-open competition (no set-aside designations across its footprint). The vendor operates a single, dominant indefinite-delivery contract vehicle with the Surface Deployment and Distribution Command and competes entirely as a prime; it has no subcontract or grant footprint.

Central Gulf Railcar Services' customer concentration is extreme and monolithic. The Surface Deployment and Distribution Command accounts for 77 of 79 total awards (98% by count) and $36.4 million of $44.7 million combined potential value (81% by dollars). Two remaining awards — one to the Department of the Air Force ($7.2 million IDIQ for DODX Freight Car Services-Material and Freight Car Maintenance) and one to the Department of the Army Installation Management Command Southwest Region ($1 million) — represent outliers. The Air Force award is the same underlying vehicle indexed through SDDC procurement authority; SDDC is the operationally dominant customer by a margin that leaves no meaningful secondary customer exposure.

The vendor's entire active footprint runs on a single parent vehicle: an indefinite-delivery contract (HTC71122DR024) with a ceiling of $7,215,145.64, awarded October 1, 2022, and running through September 30, 2026. This vehicle carries 56 delivery orders valued at $2.1 million combined potential, with monthly orders ranging from approximately $2,500 to $178,043. Cumulative delivery order values against this IDC exceed $1.2 million as of the most recent awards (April 2026). Three additional legacy IDCs (W81GYE07D0016, HTC71118DR007, and DOD Railroad Cars Repair and Maintenance 2012-2016) collectively account for $10.7 million across 19 older task orders. The active pipeline is driven entirely by the primary 2022–2026 IDIQ.

Work scope is singular and operationally focused: labor, parts replacement, comprehensive maintenance, and repairs for the Defense Freight Railway Interchange Fleet (DFRIF), a fleet of approximately 2,000 military railcars supporting domestic and international Army equipment transportation. Performance is executed at the contractor's facility in Prichard, Alabama, in accordance with military regulations and industry standards. The vendor specializes in NAICS 488211 (Support Activities for Rail Transportation) and PSC 24 (Maint/Repair/Rebuild Of Equipment—Railway Equipment), with 76 of 79 awards aligned to that PSC. Delivery orders are firm fixed-price with no set-aside designation and represent recurring monthly utilization since the IDIQ's October 2022 inception.

Activity trajectory shows spike-and-decline in recent years. The vendor received 24 awards in 2023 (the year after its primary IDIQ award), 15 in 2024, 12 in 2025, and 4 in the first four months of 2026. The recompete cliff on the primary IDIQ vehicle hits September 30, 2026 — less than twelve months from today — carrying the full $7.2 million ceiling value. This is the sole material recompete risk in the footprint. Combined obligated dollars across all awards stand at $11.6 million (26% of potential value), indicating substantial remaining capacity in the 2022–2026 IDIQ if monthly utilization continues at historical rates. The vendor has been registered in SAM since 2007 and has provided these services continuously since that time.
