LNER Class Y10

From Wikipedia, the free encyclopedia

The LNER Class Y10 was a class of 0-4-0 geared steam locomotives built by Sentinel Waggon Works for the London and North Eastern Railway and introduced in 1930. The LNER numbered them 8403 and 8404 but they were later re-numbered 8186 and 8187.

They both passed into British Railways ownership in 1948 but 8187 was withdrawn almost immediately. Number 8186 was allocated the BR number 68186, but never actually carried it, and was withdrawn in 1952.

[edit] Overview

The vertical water-tube boiler and the engines were similar to those used in Sentinel steam waggons. Each locomotive had two 2-cylinder engines, giving a total of 200 horsepower.

Final drive to the wheels was by sprocket chain. There was a two-speed gearbox but gears could only be changed while the locomotive was stationary.

[edit] Usage

These locomotives were intended for service on the Wisbech and Upwell Tramway and had several tram engine features. These included cowcatchers and sideplates and a cab at each end.

They were not a great success on the Wisbech and Upwell and both were moved to Yarmouth in May 1931 to work the quayside line.
