Steam gave way to diesel and electric as we well know

Here 4F 43924 is prepped beside Class 37 diesel

I suppose it was inevitable as life was much better

for the engine men on the diesels and electrics

The class 37 themselves have survived well with

a number still running on the Highland lines in 

Scotland.

They too, now for part of our preservation

Here a Hunslet with English Electric experimental 

'Vulcan', along with every preserved railways needs

a diesel shunter.
