   Revision of limit value for longitudinal forces in the train  evaluated  
Safety requires a limitation of the permissible longitudinal force exerted on the locomotive by the following cars. For some loco-hauled trains, this is a critical restriction for the use of regenerative braking. A more differentiated concept for the limit values for longitudinal forces could remove this barrier.
Technology field: Regenerative braking and energy management
