Diesel Locomotives 

 

From the late 1950s diesel locomotives started to replace steam traction on Britain's railway network. By 1968 the transition was complete and the diesel locomotive reigned supreme, pulling everything from the major express services to the local freights. In turn these early diesel locomotives have been replaced by multiple units.

Fortunately you can still see a wide selection of heritage diesel traction in action on the GWSR.
