Do locomotives pull or push?

It is usual to arrange matters so that the trailing locomotive supplies less power, i.e. that the locomotive at the front does more pulling than the locomotive at the rear does pushing. Having an independent locomotive, as opposed to a power car at each end, is also known in the railway world as a top and tail.

When the loco pulls the frictional force (rolling) times the bogies total weight makes the rear wheels of loco to exert more vertical force (due to moment arm) and this adds up to the loco dead weight. The pulling frictional force of loco becomes thus more than the total bogies weight times rolling friction.
