DymaxRail builds heavy-duty flatcars, equipment movers, and machinery carts from 6 to 100 tons — some self-propelled, some towed behind a hi-rail truck or railcar mover, all built to order. Explore the products below, or request a quote.
Self-propelled 44-ft utility flatcar with 45-ton capacity for hauling ballast trucks, cement trucks, and midsize excavators. Features an integrated turntable for 20-minute road-to-rail loading at railway crossings. Includes a 2-person climate-controlled cab, hydraulic ramps, and optional ballast spreader.
The largest self-propelled road-rail flatcar available — 90-ton on-rail capacity across a 53-ft lowbed deck with a 26-ft equipment well. Haul crawler cranes, large excavators, dozers, and bridge beams with a 7-minute rail crossing load time. Available in 90T and 55T capacity models with 8’6″ or 9’6″ deck widths.
Self-propelled 50-ton rail platform built to carry and support specialized maintenance equipment — aerial lifts, welders, hydrovacs, and material handling tools. Available in 48-ft and 53-ft lengths with an integrated articulating crane, powered steerable crawler tracks, and hydraulic stabilizers.
Towable rail cart for hauling cranes, cement trucks, excavators, dozers, or bridge girders to remote track — from a 3,600-lb 6-ton model up to a 100-ton all-purpose cart. Excavator Series handles tracked machines; All Purpose Series hauls wheeled or tracked loads, with up to 36 ft of usable deck. Air brakes, hydraulic ramps and stabilizers, Apitong hardwood decking, and railcar-mover coupling on larger models.
Low-profile cart built to move aerial lifts and compact machinery through transit tunnels, with side ramps for unloading where there’s no room to work off the end. Off-track rubber landing gear rolls the cart clear of the rail with no crane or lifting. Park it overnight and keep the line open. Available in 10- and 20-ton models; works with hi-rail excavators or trucks.
Self-propelled rail cart that runs on your excavator’s own hydraulics — no separate engine, no machine modifications. Lift on, lock the ramps, and travel up to 13 mph on rail, or tow it. Fits most excavator brands from 8 to 36 ton class, with load capacities to 92,500 lbs, fail-safe spring-set braking, and hydraulic stabilizers for over-side work like drilling, shearing, and sheet piling.
