O&S - ungated sign par
StoneRoad2013, on Ipernity
represents the standard UK road sign for an ungated level crossing, but apart from on the heritage / preserved lines, the UK hasn't had steam engines since 1968 !
(Oh, and it is on a Welsh Heritage Railway, and one that doesn't have any 4-6-0s on it. either !)
