When I last travelled on the Esk Valley line in 1980, Glaisdale signal box was open and staffed. Indeed, I took a very similar picture to this from the class 101 DMU that I was travelling on, see......

It's a shame that the 1904 constructed North Eastern Railway box could not be put to some sort of community use, but, having said that, the station is a little remote being some distance from the village of Glaisdale. Incidentally, Barbara Streisand singing 'Woman in Love' was number one when I last visited, this time it was somebody called Lewis Capaldi singing 'Someone Loved you'; apparantly!
