Slack action in long railroad trains can give rise to damaging longitudinal forces. This paper develops criteria for the occurrence of unplanned slack action in a unit train on a gradient change. It is shown that remote-controlled locomotives at the rear of the train can substantially reduce the incidence of such slack action. This is achieved by maintaining a unimodal draft force profile throughout the train. From these results is suggested how a train driving schedule could be determined for a particular run by considering the train parameters and the profile of the route.
