the last 'Royal Scot', 1964

"The last active Royal Scot 4-6-0 No. 46115 'Scots Guardsman' looking the worse for wear heads north past Carpenders Park [Hertfordshire, England] station in the summer of 1964, almost certainly May 9th."

If that looks like a London Underground track in the foreground, it is.
