7 Jan 2001, Berwick, England, UK
Royal Border Bridge in Berwick upon Tweed. The East Coast Main Line crossing the river Tweed before continuing into Scotland a few miles north. Two trains happen to be on the bridge at the same time. As emergency timetables are in place at that time, I cannot say whether this also happens regularly.
