RRVs have a long history, but until now, the transmission mechanisms used have been heavy, energy inefficient, and cumbersome.
RailPro have patented a unique system where the engine power is transmitted through the gearbox as per normal road use. A transfer box is located between the gearbox and the truck differential. This is used to divert power via a conventional drive shaft through to the rear rail axle.
Design Excellence Awards!! RailPro’s DSDS™ System was recognised with an SABS Design Excellence Award in 2009.
✓ A large “rigid” road-going truck, with retractable rail wheels, can run on rails, as it would on a road
✓ Direct drive through truck's gearbox to the rear rail wheels
✓ Active use of truck's existing suspension; Front suspension provided by RUBAX axle while on rail
✓ Speed is dramatically increased
✓ The truck's braking system is used to slow the vehicle
✓ Lightweight - the rail gear mass is approximately 65% lighter than existing products
✓ Ground clearance almost double that of competitors
✓ Rail gear is fully “deployable” and “retractable” in minutes
✓ Simple, efficient driveshaft system - direct drive through truck's gearbox to the rear rail wheels
✓ Active use of truck's existing suspension while on rail
✓ The truck's braking system is used to slow the vehicle
