LNER Class Y11 was a class of petrol powered 0-4-0 locomotives built by Simplex and introduced in the years 1919-1925 for the London and North Eastern Railway (LNER). Their British Railways numbers were 15097-15099.

Numbering

  • Works no. 1931, LNER no. 8430, re-numbered 8188, BR no. 15098 or 68188
  • Works no. 2037, LNER no. 8431, re-numbered 8189, BR no. 15099 or 68189
  • Works no. 2126, LNER no. ED/L4, BR no. 15097
    • Built ? acquired by LNER 1925 (ex-Preston Water Works, Lancashire), withdrawn 1950

Specification

  • Wheel arrangement: 0-4-0
  • Weight: 8 tons 0 cwt
  • Wheel diameter: 3ft 1in
  • Min curve negotiable: 1 chain
  • Engine type: Dorman 4JO (petrol)
  • Engine output: 40hp
  • Power at rail: 24hp
  • Maximum speed: 7 1/2mph
  • 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 locomotives has been preserved but several similar ones have, including:

Nottingham Transport Heritage Centre also has another Simplex numbered 15100. This is probably an "imaginary" British Railways number, continuing from 15099.
