Their [[British Rail]]ways numbers were '''15097-15099'''. ==Numbering== * Works no. 1931, LNER no. 8430, re-numbered 8188, BR no. 15098 or 68188 ** Built 1919, acquired by LNER 1923 (ex-[[Great Eastern Railway]]), withdrawn in 1956 * Works no. 2037, LNER no. 8431, re-numbered 8189, BR no. 15099 or 68189 ** Built 1921, acquired by LNER 1923 (ex-[[North British Railway]]), withdrawn in 1956 * Works no. 2126, LNER no. ED/L4, BR no. 15097 ** Unknown built date acquired by LNER 1925 (ex-Preston Water Works, Lancashire), withdrawn in 1950 ** The [[RCTS]] document ''[[North Eastern Region of British Railways|BRITISH RAILWAYS, NORTH EASTERN REGION]], LOCOMOTIVE ALLOCATION, 6th May 1950'' records this locomotive as working at West Hartlepool (Creosote Works). ==Specification== *Wheel arrangement: 0-4-0 *Weight: 8 tons 0 cwt *Wheel diameter: 3 ft 1in *Min curve negotiable: 1 chain *Engine type: [[W.H.Dorman & Co|Dorman]] 4JO (petrol) *Engine output: 40 hp *Power at rail: 24 hp *Maximum speed: 7½ mph *Brake type: Air on loco, no train brake *[[Route Availability]]: 1 *Heating type: Not fitted *Multiple coupling type: Not fitted *Transmission: Mechanical, 2-speed Dixon Abbot ==Preservation== None of the LNER Class Y11 locomotives has been preserved but several similar ones have, including: * Works no. 2029 at the [[East Anglian Railway Museum]] * Works no. 2028 at the [[Nottingham Transport Heritage Centre]] Nottingham Transport Heritage Centre also has another Simplex numbered 15100. This is probably an "imaginary" British Railways number, continuing from 15099.
