In Scotland there were a number of odd loco hauls in addition to what has already been described, I have seen photographs of the following:
Duchess Pacifics:
Glasgow to Edinbugh via Shotts stopping services
Ayr to Glasgow relief when the Open was on at Prestwick.
LNER Pacifics:
Also on Glasgow to Ayr Reliefs, Corkerhill was well known for "borrowing" Leeds based locos for fill in turns.
Perth to Carstairs portion of the WCML postal
Everything up to and including A4s worked the Fish Specials between Aberdeen and Edinburgh.
An additional Locomotive Exchange working was 34004 ’Yeovil’ from Perth to Inverness on the 13th and 14th July 1948, paired with an LMS tender and an LNER dynamometer car, just needed a Hawksworth Brake to complete the "4"
