A day on the Great Central at Loughborough

Class 37 diesels already seemed ugly and old-fashioned by the 1970s, yet they have outlasted pretty much every other class of locomotive that was around in those days.

There is at least one passenger service (Norwich to Great Yarmouth) still hauled by them.

I also came across a preserved one on the Great Central at Loughborough a couple of Saturdays ago.
