Oh how I wish I
could say that, Rob!
Andy - have you come across a relatively new book entitled 'The Early Years of the Motor Rail & Tram Car Company 1911 - 1931' by WJK Davies (Plateway Press)? This contains a good history of the development of the standard gauge shunters along with some nice plan/side/endG.A. drawings to scales of approx. 8 and 9mm/ft, and should
definitely go on your shopping list!
I've also dug up a couple of big drawings from my cave - one a full size copy of MR&TC Co G.A. Z588 (28mm /ft) side/end elevations of the British Rail examples. It is titled 'Main Line Type Shunting Loco'. This drawing does not appear in the above book, but is the very machine you're after modelling. Also a MR&TC Co outline drwg (to 13mm/ft) of LNER 8430.
I can't recall where I got these large plans, but they are stamped copyright British Rail / Oxford Publishing, so may still be available (anyone know what happened to the OPC Plans Service?).
I'd like to express a great interest in having a couple of the industrial type locos (40 / 60hp) with basic bodywork with cast ends.
So - if we cannot get Chris Klein of Ixion excited about the prospect of producing a RTR version (and I just
know it would be as successful as the Fowler infernal combustion shunter), how about a
WT 'Project' Locomotive Kit in similar vein to MRJ's Wantage Tramway loco?
Tony
Edit - ah, see the main man from Titfield has beaten me to it!
