Abstract
A computer-implemented method for optimizing locomotive assignments on a railroad network. The locomotives are assigned to power and signaling classes, based on equipment installed within each locomotive. An objective function is set forth that considers the cost of moving extra power in the network, the penalties incurred for late train departures due to the failure to assign an appropriately-equipped locomotive and the cost of train operation. Various constraints are set forth that must be taken into consideration when optimizing the objective function.
