Having found myself with a rolling road requirement, I looked on the Gauge 3 Society web pages, and perhaps it is me, but I cannot find anything relating to the profiles as defined by CODE 250 which is what Cliff Barker appears to have standardised his track on.
I can find a 'track standards' .pdf - but that document that describes wheel profiles and is therefore NOT a track standards guide to my mind.
If anybody can point me in the right direction for a document outlining the dimensions for CODE 250 (and any other coded rail used in Gauge 3 or 3 2/3£ gauge ) I'd be very happy to take your advice.
Many thanks
Robert
