LNER class A3 4-6-2 No 60084 Trigo departs from Leeds City with the 'North Briton' for Glasgow Queen Street in the 1950s. B16/1 No 61436 waits alongside as engine crews discuss Trigo's performance. It is after February 1952 as the B16 has moved to York 50A shed but I would estimate not many years after that date.
