They are placed between very long sections of continuous welded rail or at the transition from continuous welded rail to jointed track, and commonly in the vicinity of bridges, viaducts and tunnels where the ...
The system is fully regenerative: all of the engine's power reaches the track either through the main driveshaft or the steering system; none of the energy is being lost to brakes or clutches. Additionally, since power is fed around the transmission to the steering system, in some designs the tank can be turned or even pivoted in place even ...
