Glyn Valley Tramway Locomotives 16mm scale drawings (Second Edition)
Covers all the locomotives used on the line from when it was being built, but concentrates on the Beyer Peacock tram locomotives and the later Baldwin 4-6-0, which also benefits from a dimensioned drawing.
This is a second edition, and I am not sure what changes have been made since the first edition appeared in 2007, but one minor error in one set of drawings remains. Its not that major, but as drawn the engine certainly couldn't move! That said, if you want detail on the GVR locomotives, this is very useful.
44 pages of drawings and B&W photos. Paperback.
