FRA Awards $16.2M to Deploy First Autonomous Railcars on a US Public Short Line

The Federal Railroad Administration has awarded a $16.2 million CRISI grant to the City of Columbia, Missouri to deploy Intramotev's TugVolt autonomous, battery-electric railcars on the Columbia Terminal Railroad — a 21.4-mile short-line connecting Centralia to Columbia that carries freight across public highway crossings and is subject to full federal rail safety oversight. The award moves TugVolt from a track record of private, unregulated industrial lines onto a public mainline for the first time, setting up what could become a safety compliance template for more than 600 short-line railroads across the United States.

The distinction matters more than the dollar figure. Every prior TugVolt deployment — at a Carmeuse Americas mining railroad, a Watco Companies transload terminal, and an R.J. Corman Railroad facility — has operated on captive, private lines outside FRA jurisdiction, where no federal grade-crossing rules apply. Columbia Terminal Railroad, known as COLT, is an FRA-regulated Class III carrier with public highway-rail grade crossings on its route. That difference means that for the first time, a TugVolt railcar will need to detect approaching road vehicles, coordinate with crossing warning systems, and stop safely in situations where the FRA, not just a private landowner, has authority to investigate any failure. No existing FRA rulemaking specifically addresses fully autonomous freight railcar navigation through public grade crossings — the COLT deployment will begin writing that rulebook.

How TugVolt Turns Any Standard Freight Car Into a Self-Driving Train

TugVolt is a retrofit kit, not a replacement railcar. Three bolt-on modules convert any existing standard freight railcar into a self-propelled, self-navigating vehicle that requires no locomotive. The first module is a sensory and location stack combining GPS positioning with computer vision and object-detection systems that give the car awareness of its surroundings. The second is a 266 kWh battery energy storage pack. The third is an electric propulsion drivetrain with regenerative braking — energy captured during deceleration feeds back into the battery, reducing net energy consumption over a shift.

Intramotev's software platform organizes operation into three ascending tiers. Manual mode is human-remote-controlled. Full Autonomy mode handles coupling and decoupling with other cars, automated air brake testing, and activation of horn, bell, and lighting systems as required by railroad rules. Fleet Autonomy mode — the most complex tier — enables simultaneous coordinated dispatch of multiple TugVolt units, with train-to-train safety communications and integration with wayside signal infrastructure. The COLT deployment will begin in Phase 1 under supervised manual and limited-autonomy operation before progressing to Phase 2, which the company describes as Full Autonomy mode on revenue runs.

Two hardware generations are in the field. Gen2 operates at up to 12 miles per hour and can move up to 10 cars. Gen3 is rated for 60 mph and 16 cars — speeds and capacities relevant to actual interchange freight service rather than yard switching. Both generations use the same 266 kWh battery and share the company's claimed range of approximately 300 miles per charge at roughly one hour to recharge, though those figures are company-reported and have not been independently verified.

The Grade-Crossing Problem That Makes COLT Different

The approximately 128,000 public highway-rail grade crossings in the United States represent both the operational scope of the short-line network and its most hazardous interface with road traffic. Grade crossings are the site of the majority of railroad accidents involving road vehicles, and they introduce a category of unpredictability that enclosed yard or captive-line operation does not: cars that stop on the tracks, pedestrians who misjudge a train's speed, emergency vehicles responding to incidents, and agricultural equipment that moves slowly across rural crossings.

For an autonomous railcar to operate through these intersections under FRA oversight, its detection systems must perform reliably in adverse weather, low-light conditions, and situations not anticipated in its training data. Intramotev has not publicly released technical specifications for TugVolt's grade-crossing detection protocol, and no independent evaluation of that system's performance has been published. The FRA-supervised Phase 1 on COLT will likely be the context in which that data is generated. Columbia City Utilities Director Erin Keys said the federal investment would allow the city to modernize COLT, strengthen customer service, and position Columbia as a leader in rail innovation. Intramotev CEO Tim Luchini said autonomous railcars "can help them serve more customers, more often, at lower cost, and this program will show what that looks like on a working mainline."

The City of Columbia, which owns COLT through its utilities department and connects the railroad to Norfolk Southern interchange freight at Centralia, is the named grant recipient — a common structure for CRISI awards, which favor public or quasi-public entities as lead applicants. The arrangement pairs a municipal operator's incentive to improve service with a private-technology company's interest in proving its system under federal oversight.

Intramotev and Parallel Systems Are Racing Toward the Same Public-Line Milestone

Intramotev is not alone in pursuing autonomous freight rail on US public lines. Parallel Systems, a Los Angeles-based start-up founded by former SpaceX engineers, raised a $100 million Series C in October 2026 and is currently running an FRA-supervised pilot on track operated by Genesee & Wyoming in Georgia. Its approach differs substantially from Intramotev's: rather than retrofitting standard freight railcars, Parallel Systems has built lightweight, purpose-designed autonomous platforms that travel uncoupled in platoons and are intended to carry shipping containers between intermodal terminals.

The two companies represent competing architectural philosophies. Intramotev's retrofit model lowers the barrier to adoption — a short-line operator installs TugVolt modules on cars it already owns, rather than purchasing an entirely new vehicle type. Parallel Systems' clean-sheet design allows optimization for its specific platoon-autonomy use case but requires customers to accept a new railcar form factor. Neither company has yet published independently audited performance data for mainline public-line operation, because neither has yet completed a commercial deployment in that environment. The CRISI award gives Intramotev a significant institutional advantage: FRA is simultaneously the grant funder and the safety regulator, meaning a successful COLT deployment would put Intramotev in the room when the agency begins writing the rules that will govern the entire sector.

A $3.6B Short-Line Sector That Cannot Easily Find Train Crews

The business case for autonomous freight rail converges on a structural problem in the US short-line industry. The approximately 600 Class III railroads that form the final-mile layer of the US freight network collectively generate roughly $3.6 billion in annual revenue and employ around 12,430 workers, according to IBISWorld's 2026 sector data. Short lines operate on thin margins, often serve rural communities with limited labor pools, and face difficulty attracting and retaining certified locomotive engineers — a profession that requires federally mandated training, licensing, and rest requirements.

TugVolt's retrofit model addresses this directly: a self-propelled railcar operating under Fleet Autonomy removes the need for an on-board or cab-based engineer on the equipped car, potentially allowing a single dispatcher to manage multiple rail movements simultaneously. The economic arithmetic — replacing a chronic labor constraint with a battery-electric autonomous system — is the proposition Intramotev has been proving on captive lines and is now attempting to validate under the scrutiny of FRA regulation on a public railroad.

Whether the COLT deployment succeeds in generating a replicable safety model will determine whether autonomous freight rail remains a niche application for industrial yards or becomes a practical option for the broader short-line network. FRA has not yet published a proposed rule for fully autonomous railcar operation through public grade crossings; a completed COLT deployment under federal supervision would likely become the primary evidence base for any such rulemaking. The agency will be watching how TugVolt handles a public Missouri rail crossing, and so will the operators of the other 600 short lines that could eventually follow.
