Genset locomotive

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

General

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.

Advantages

save fuel, wear & tear, noise, pollution, etc., when excess engines can be turned off.
one size engine is needed rather than different engines for each power range.
should one genset engine fail, the others can keep the train going, albeit at reduced speed.
to remove a genset engines, only a "medium" size crane is needed.
to remove a normal engine, a "large" size crane is needed.

Disadvantages

more complex design, but this would cease to be a problem once the design is debugged.

Greater capital cost offset by lesser operating cost.

Greater deadweight, however locomotives may carry extra heavy ballast to maximise tractive effort.
