The Sacre GCR Class 12A 2-4-0 Locomotives
Although Sacre designed a number of 2-4-0 types for the Manchester Sheffield & Lincolnshire Railway (MS&LR, later GCR), No. 169B of his Class 12A was the only one to survive into LNER ownership. Twenty eight 12As were built in three batches in 1875, 1884, and 1885. The design was a typical Sacre design with double frames and a round-topped firebox.
Robinson rebuilt the 12As with new boilers in the early 1900s. No. 169B received its new boiler in 1902. A flush firebox and combination injectors were also fitted.
The 12A locomotives were initially allocated to the Cheshire Lines, and received a good reputation as fast locomotives. Contemporary timetables show 12A-hauled services scheduled to run from Manchester to Warrington (15.7 miles) at an average speed of 52.5 mph. Later in life, the 12As moved to secondary work. No. 169B spent its last years at Annesley shed, hauling the staff train ("The Dido") to/from Bulwell Common.
The GCR Class 12A is sometimes described as LNER Class E3, but there is no evidence that this was an official class designation. Although there is a gap in the LNER classification scheme, No. 169B was withdrawn in June 1923 before 'E3' could be used.

None of the GCR Class 12A locomotives survived into preservation.
I am not aware of any models of the GCR Class 12A locomotives.
