I decided that after rebuilding my class 201 it should have something to do. Rather than build the same carriages that Dfenz already has I thought I'd do some freight cars. After some searching I found pictures of 'spoil cars' that are used for maintenance and I liked the colour scheme of them.
The model is mostly done but the underside still needs a bit of work:
