GWR Class 9400 0-6-0 Pannier Tank

Built 1947-55, Designed by Frederick W. Hawksworth.

Total Number Built 210 - Total to BR 210

Introduced 1947. Hawksworth taper boiler pannier tank design for heavy shunting duties. The first ten (the only ones built by Swindon Works, the rest being built by contractors) were superheated. Classification 4F.

(a) 9410-9489 Introduced 1949. Locomotives with non-superheated boilers.

Further to a request for more 5700 Class pannier tanks in 1947, the General Manager of the Great Western Railway, Sir James Milne, insisted that a more modern looking locomotive should be constructed. This resulted in Hawksworth producing the 9400 Class with the No. 10 taper boiler.

The engines were not so easy to operate whilst shunting as the controls were not as accessible as in the 5700 Class. They were also heavier than the 5700' and had to be restricted over some routes. However, inspite of their disadvantages, British Railways built a total of 210, the last ones appearing as late as 1956 which gave them very short lives.

Only the first ten were built at Swindon under the GWR in 1947, the others being constructed by various contractors.

Some locos were based at Bromsgrove Shed for banking duties on The Lickey Incline. Loco No. 9401 was loaned to the Eastern Region for trials in 1957. Based at Stratford shed it was used in Temple Mills Marshalling Yards, London.

Many of these engines were withdrawm with less than ten years of service.

Two 9400 Class locos 9400 and 9466 are preserved.
