I always assumed the way I do at at Winchcombe is the correct way, but I've started looking recently and it seems that it's not the only way. The way we do it is the black middle is the same width as the total waist (black+yellow) line on choc 'n' cream/blood 'n' Custard stock, with the yellow either side being about a quarter of an inch thick. Is this right? Other railways seem to have the yellow thicker - not sure whether that makes the black line thinner or the total line thicker - and/or the yellow actually more of a gold, as opposed to the "buttercup" yellow I think we use from Williamson's. Also some railways appear to use some sort of "tape" rather than "doing it properly" with a small paintbrush and a steady hand (or masking tape) Maybe those railways that feel they can't paint the line themselves are restricted by what's available? What are people's opinions on this, as to both what is correct and what is more aesthetically pleasing (not necessarily the same thing!) Obviously I'm in favour of the way we do it on the GWSR, I think it looks good, and even if it's wrong, is at least produced right, rather than just with tape.
