Introduced in 2010, Generation 4 Rail King mobile railcar movers feature RoyalGlide, a new no-maintenance, three-point platform suspension system that virtually eliminates rail shock and vibration to the cab. The result is exceptional ride quality and performance.

In addition to RoyalGlide, key benefits of Gen-4 Rail King railcar movers are simplified power train and hydraulic systems.

The power train links a Cummins QSB Tier III engine and Funk DF 150 4-speed transmission, and John Deere axles with no spin, inner planetary gear sets and wet disc brakes. Free-floating mounts allow axles to move up and down in the frame, enhancing traction. Four large rubber isolators protect from rail shock and provide a smooth ride.

The hydraulic system features a single pressure-compensated hydraulic pump, simple push button controls and a central monoblock for ease of service.
Gen-4 Rail King includes standard Gen-3 features, including the Stewart & Stevenson patented cushion coupler system, both road wheels and rail wheels, both side-mount and full-width cabs, and center console with easy view instrument panel. Gen-4 Rail King is available in six models.
