Genset locomotive

A Genset locomotive is one where a number of smaller diesel engines are used rather that a single large engine.

A locomotive builder may make a range of locomotives of different power, with the lowest power shunter with, say, one genset engine, and the highest power main line freight locomotive with several genset engines.

The excess engines are turned off when the extra power is not needed.

The different genset engines do not have to be the same size.
