Glenderg Posted March 8, 2013 Share Posted March 8, 2013 Was there a standard size for these? 254mm (10")or 305mm (12") were the standard sections available at the time, and in converting to 00 it's either 3.2 or 4.0mm - a substantial difference.

0 islandbridgejct Posted March 13, 2013 Share Posted March 13, 2013 There's a drawing in Ernie Shepherd's book on the Midland that shows them at (I think) 4mm. I'll check up when I get home and see if I can find anything else. I'd imagine John could help you in relation to more recent stock, given his 20ft container flat kit, but they look similar to me.

0 Mayner Posted March 15, 2013 Share Posted March 15, 2013 (edited) I never checked just take a tracing off the GA and reduce it to OO:D Its seems to have varied between 9" & 11" depending on the type of vehicle, 9X4 timber and 9X3½ channel seems to have been common enough for wagons.

0 islandbridgejct Posted March 20, 2013 Share Posted March 20, 2013 Sorry I'm slow getting back on this. Drawings show 4mm iron solebars on Midland wagons from the late 1890s. GSWR ones seem the same. If you want to measure one, the wagon under the crane at Mallow is a standard GSWR underframe on 3'6" wheels. For CIE 4 wheelers, the older ones seem to have narrower frames.
