When double-heading a train, two locomotives are used at the same end—historically with separate crews.A double headed U.S. passenger train of the 1860s at Dale Creek Crossing near Sherman in southeastern WyomingA double headed steam excursion train in Iowa, September 2006
In railroad terminology, double heading indicates the use of two locomotives at the front of a train,[1] each operated individually by its own crew. The practice of triple-heading involves the use of three locomotives. The practice of multi-heading involves the use of multiple locomotives and so on.
Double heading is most common with steam locomotives, but is also practised with diesel locomotives. It is not strictly the same practice as two or more diesel or electric locomotives working 'in multiple' (or 'multiple-working'), where both (or all) locomotives are controlled by a single driver in the cab of the leading locomotive.
