In the very last rays of the setting sun, 37409 Loch Awe rounds the reverse curves at Achallader on 20 July 1997 with the 1B01 19:50 Fort William to Euston ScotRail sleeper, which the 37 will work as far as Edinburgh. Obviously no one would actually be trying to go to sleep this early in the evening, which is just as well as I could never work out how you could possibly get to sleep with a 37 at the head of the train!
