   Regenerative braking in freight trains  evaluated  
Due to high average weights of freight trains and the fact that only locomotive axles are powered, high shares of braking power comes from the mechanical brakes in the freight cars, and only a small share is added by the locomotive itself. Based on conventional freight trains, there exists limited potential to raise the share of recovered braking energy.
Technology field: Regenerative braking and energy management
