Belmond 67024 passing Lewes with ECS passes Southern 377 30 4 2022

This view is of the rear end of both trains. The Belmond Pullman train travels with a diesel locomotive at both ends. Along the south coast there are several stations, including Littlehampton, Bognor Regis and Eastbourne which are termini at the ends of branches off the main west to east coast lines, so rather than have to have the engine run round its train each time, it is simpler to have locos at both ends. There is the added reassurance that in the event of a failure the second engine can power the train. In days gone by there were many more engines about that could be substituted. Now most passenger trains are multiple units and there can be incompatibility between couplings and control systems so sometimes even they cannot help each other if one fails.
