L&YR 111 class

The Lancashire and Yorkshire Railway (LY&R) Class 111 0-4-4T were designed by Kitson and Company for William Barton Wright, who had a requirement for a short-distance passenger tank locomotive.[1]

Design and construction

On his appointment in to the LY&R in 1875 Barton Wright inherited over 800 engines of more than 30 different types and many were insufficiently powerful for their required duties and resolved the L&YR would target achieving a minimum number of standard locomotive types with interchangeable components in order to meet future traffic needs.[3] He addressed the most urgent needs for freight locomotives and higher end passenger locomotives first before addressing the requirement for a short distance passenger locomotive in 1877.[4] The 0-4-4T was essentially a Kitson design with 5 ft 8 in (1.73 m) coupled wheels, and Kitson delivered the first 12 locomotives between April 1877 and July 1878. The first pair, Nos. 111 & 112 had extended side tanks whose weight restricted the route availability of the engines so subsequent locomotives were delivered with shorter side tanks.[2]

Subsequent batches were ordered from different manufactures and some included some detail variations. Ten came from Dübs & Co. from September 1978. Ten more from Neilson & Co. from August 1879 but had even smaller tanks and a water capacity of 900 imp gal (4,100 l; 1,100 US gal) and had a total working weight of 46 long tons 4 cwt (103,500 lb or 46.9 t). The final batch of 40 from Sharp, Stewart & Co. arrived between October 1885 and August 1886 with a working weight of 52 long tons 4 cwt (116,900 lb or 53 t).[2]

The rear bogie, of an Adams type but with Timmis springs compressed to 30 long cwt (3,400 lb or 1,500 kg) replacing the indiarubber side check springs and the large indiarubber pad being omitted. It was said to give "steady running" at the rear of the locomotive.[2]

Service

The original locomotives, Nos. 111 and 112 with long side tanks were found to be heavy and generally were allocated to pilot duties at Manchester Victoria.[6] Others were initially allocated for expresses from Manchester to Leeds, Hellifield and Manchester before later being displayed by 4-4-0 tender locomotives to local services.[7] Bulleid, in the biography The Aspinall Era the class is commended on "doing grand work".[1]

Notes
  1. Kitson and Dübs engines with short tanks; Neilson engines had 900 imperial gallons (4,100 l; 1,100 US gal) tanks
