Radio-controlled double traction in freight trains

evaluated

In heavy freight trains operating in double-traction, radio-control can facilitate an optimised use of regenerative brakes.

Technology field: Regenerative braking and energy management



General information

	Description
		In heavy freight train operation with several locomotives (double- or multi-traction), radio-control between the locomotives can save production costs and permit an optimised use of regenerative brakes. Such a system is used on the alpine transit service over Swiss Gotthard where heavy freight trains are operated in double-traction (one locomotive at the front end and one at the rear end of the train). SBB has equipped four engines type Re 460 (with high performance of electric recuperation by braking) with a radio control. This way only the front locomotive has to have a driver on-board, the other one is operated via radio control.
