Steam on the Derwent Valley Railway

A couple of years ago I posted a video of a diesel freight train on the Derwent Valley Railway from the late 1970s:

When I was an undergraduate at York, the bus from the university into the city used to cross a bridge over an overgrown single-track railway. 

This was the Derwent Valley Light Railway, which in those days ran from Layerthorpe in the city for four miles out to Dunnington. When it opened in 1913 it had run almost to Selby: in 1981 it was to close altogether.

The video here shows one of the line's short-lived steam workings for tourists in the same era.
