CR 4-2-2 No 123 makes a lovely sight with the two restored Caledonian carriages near Breich, on the Glasgow to Edinburgh Princes Street line having worked the SLS Angus Railtour.
Presumably this is the returning railtour which ran as two trains from Broughton Ferry, 54486 on reporting number 171 and CR 123 on 172 as seen here.
