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.

|
|
Potential for increased use of regenerative braking in freight operation is limited. A thorough assessment of status quo is needed for each fleet to identify potential to be exploited without major technological investment. Possible measures range from a revision of regulations for longitudinal train forces to radio-controlled double-traction. |
