Dymax Rail Rider SC high rail transport vehicle

Move Large Machines & Equipment Over the Rails

The Dymax Rail Rider SC (Self-Contained), formerly known as the T-Railer, gives you more power and more capacity as the world's most verstaile low bed equipment transporter for the rails. Featuring high rail gear built into the work platform, the Rail Rider SC moves on rail at speeds up to 17 miles per hour.

It optimizes productivity and lets you tackle new jobs, whether you're moving excavators, dozers, backhoes, skid steers, wheel loaders, crawler cranes, wheeled cranes, ballast trucks, vacuum trucks, undercutters, tampers, concrete trucks, drilling rigs, ties/sleepers, panels or general maintenance equipment.

You can either move the Dymax Rail Rider SC like a conventional trailer, or low-boy from the job site and load to the rail tracks in 15 minutes or less with the optional integrated turntable. Haul equipment and machinery to and from remote locations with ease. Excavators can also work from the platform with the built-in stabilizer system.

Save Money & Perform Multiple Jobs

The Rail Rider SC allows you move large machines on rail without the need to modify undercarriages with high cost rail adaptation systems.  You can use standard machines and move your entire fleet with one Dymax Rail Rider SC! Perform a variety of tasks without investing in expensive machine-specific equipment. Spread ballast, set transmission poles, haul drainage pipe, transport excavators and loaders, cement trucks, rail, panel sections, scrap ties, cement trucks and cranes, and more with the Dymax Rail Rider SC.

Whether you're a Class I or Class II railroad, a regional, a short line, a mass transit, right of way maintenance contractor or a city terminal railway, the Dymax Rail Rider SC will save you time and money. This self-contained rail transporter eliminates the need to purchase or rent a special machine each time you need to operate an excavator, truck, crane or any machine on rail.

Efficiency, Technology and Performance

Dymax Rail Rider SC machines are operated with remote control technology and powered by an independent hydrostatic drive. Operators can work from within the cab or from the outside of the machine. Every Rail Rider SC has air brakes, safety lights, lighting packages, tie down locations, camera systems, and a toolbox. Rail Rider SC machines are registered with vehicle identification numbers (VIN) and include road gear for pulling on highway. Some models require special permits for pulling on highway; please contact Dymax for more details.

Available in two base configurations, all Rail Rider SC machines are custom engineered to suit your specific railway application needs. Call Dymax today to speak to a railway specialist!
