Mel,
The 57 really does look great and makes me want a G3 line. No chance of course, but I can dream. The idea of having the narrow gauge line fior playing trains, but a real life GW branch in the garden is a beautiful thing to aspire to!
Where did you get the George Turner figures? I can't find any reference to them on the Web.
Congratulations, that's one awesome loco, as they might say over here!
