Daniel's shot is of Deltic class 55, 55022 Royal Scots Grey travelling light engine through Bank Quay on 24th August 2010. The working was Bury - Crewe.
A class 56, 56108, in BR large logo livery, is shown in Bill's pic, taken at Winwick on 23rd May 1992.
The third pic, from Geoff Monks, features a northbound Pendolino in the snow at Bank Quay on 18th December 2010. The coupling gate is open and Geoff thinks that it may have frozen in this position due to the sub zero temperatures.
