Double heading refers to a situation where two locomotives are used to pull a train together, often to provide extra power for hauling heavy loads or traveling on steep inclines. This setup allows both engines to share the workload, helping the train move more efficiently. Double heading is typically used when a single locomotive may not be powerful enough to handle the train's weight or track conditions.
