Career edit

30 engines, designed under the supervision of C J Bowen-Cooke, and built at Crewe during 1911–1917. Intended for duties formerly needing two locomotives. Essentially a tank version of the G class 0-8-0s. When introduced they had the then new style of 12 in (300 mm) letters for the company's initials on the tank sides. They were fitted with saturated "Precursor" class boilers with lagged ends, round-top fireboxes, and sloping coal bunkers.[4] The main wheels were coupled by three overlapping rods and the third pair of wheels were flangeless. Lever actuated Joy reversing gear appeared in-lieu of the normal Ramsbottom screw system. The earlier engines initially had slender tapered Cooke buffers but these were replaced by those of standard Webb pattern: The latter type was fitted from new on later engines. Braking was by steam, but vacuum brakes were provided to operate fitted or passenger stock if required.[1]

No. 7892 in 1948, heading a line of ex-LNWR locomotives awaiting scrap at Crewe Works

During the Depression years many of the class spent time in store for want of work and almost half were scrapped. Ten, however, survived to be taken into nationalised stock at the start of 1948.[9]

No. 1090, as BR No. 47884, achieved the highest calculated service mileage of 732,425 mi or 1,178,724 km. Others ran 715,830 mi or 1,152,020 km (No. 47896), 701,005 mi or 1,128,158 km (No. 47877), 692,706 mi or 1,114,802 km (No. 47881) and 553,433 mi or 890,664 km (No. 7885).[9]
