Whitby, Redcar & Middesborough Union 0-6-0 Locomotives in Great_Britain
Class Details by Steve Llanso of Sweat House Media
Class Minnie (Locobase 11190)
Data from the East Essex Locomotive Preservation Society website ([
], last accessed 3 April 2010). Works number was 358.
Locobase wonders if the 713 sq ft figure isn't a simple typo - data from other Fox Walker engines of the time suggest the number could be 413 sq ft.
The East Essex site offers as a guess the use of this locomotive in the construction of the Easington Tunnel on the railway shown above. (The WR & MU broke ground on 29 May 1871, courtesy of Maria, Marchioness of Normanby, but was only completed to Whitby in December 1883.)
After its stint as contractor locomotive, the engine was sold to Skinnington Iron Works, where it served in obscurity for over 80 years until 1963.
Remarkably, the Minnie still had some miles to spend in her frame and went to work on the Kent & East Sussex museum road for 20 years, then on the East Kent and the Mangapps before coming into the EELPS fold. According to the site, there were no plans to restore Minnie to running condition.
