caption_attribution_description: English: Ex-GCR Class 9L 4-4-2T at Ardsley Locomotive Depot. Ardsley Depot was a large one, with 93 locomotives in 1947, providing motive power for the busy freight and coal traffic on the ex-Great Northern lines in the area based on Lofthouse Marshalling Yard and some passenger traffic between Wakefield, Leeds and Bradford. The complement in 1947 comprised:- 7 4-6-0, 5 2-8-0 (LMS-type), 9 0-8-0, 30 0-6-0, 9 4-4-2T, 3 0-6-2T, 30 0-6-0T. No. 7451 depicted here was a Robinson C14 4-4-2T.
context_page_description: The Great Central Railway 9K and 9L classes were two related classes of 4-4-2T Atlantic steam locomotives. They were both intended for suburban passenger services. After the 1923 Grouping, they served the LNER as classes C13 and C14.
  Their designer was John G. Robinson. The design was based on the earlier Pollitt Class 9G 2-4-2T locomotives, but with a lengthened boiler and a leading bogie to carry it. This extension of running gear also resembled an early Robinson design for the Irish Waterford, Limerick and Western Railway.
  All passed into British Railways service and the first was not withdrawn until 1952. Most were withdrawn between 1955 and 1959. The last examples of each class, 9K 67417 and 9L 67450, were scrapped in 1960. None were preserved.
context_section_description: A further twelve locomotives were built by Beyer, Peacock & Co. in 1907. These were of basically the same design, but had enlarged water and coal capacity. They were designated 9L by the GCR and later C14 by the LNER.
  The side tanks were enlarged for an extra 375 gallons, by widening their side plates. Overall width across the tanks increased from 8' 6" to 8' 9". This gives rise to a visible recognition feature in photographs: the 9K have tank and cab sides in a flat plane, the 9L tank sides project slightly.
  Coal capacity was also increased by raising the rear wall of the bunker with a semicircular extension.
  The boilers were the same as for the 9K. All were built with saturated boilers and, as for the 9Ks, were rebuilt with superheating as their boilers were replaced. The first to be superheated was Nº 1122 in 1914, although this was not a new boiler and only lasted until 1923 when it was replaced by a saturated boiler. All were converted under LNER ownership, from 1926 to 1935. Water pick-up gear and shortened chimneys to fit the LNER loading gauge were removed and changed as for the 9K class.
