Abstract

We consider energy-efficient scheduling of freight trains on a line with single-track sections, as is the case on many freight railways routes in North America. We determine the train speed that minimizes the energy consumption, taking into account the departure and arrival times and exploiting the waiting times. The proposed energy consumption model takes into account the ground topography, the speed, the number of axles the axle load and the type of locomotives. Some experiments are conducted in order to estimate the energy gain when adapting the train speed, using Canada Pacific Railway (CPR) data.
