Steam locomotive, London & South Western Railway, M7 class 0-4-4T No 245, designed by Dugald Drummond, built at Nine Elms in 1897, withdrawn in 1962.
Locomotive No. 245 is an example of the London & South Western Railway’s M7 class, designed by Dugald Drummond. A passenger tank locomotive, No. 245 was designed to cope with the busy London network, one of 105 built for this purpose.
The M7 tank class was the first design by Drummond when he took over as the Locomotive Superintendent of the London & South Western Railway in 1895. The M7 proved to be a successful and long-serving class of locomotive, lasting in service until 1964. Due to this, the design was adapted to accommodate new technology.
After the 1923 Grouping these locomotives continued to serve on the new Southern Railway, and subsequently British Railways after nationalisation in 1948.
On 13th April 1948, an M7 locomotive was involved in an incident at the Armstrong Lift on the Waterloo & City Line. As there was no ground level section of this Underground line, a hoist was used, manufactured by Armstrong Whitworth & Co. Coal wagons were being loaded onto the lift at the upper level, but some of the supports were not properly engaged and the platform tilted, sending the wagons and locomotive No.672 falling down the lift shaft. The locomotive and wagons had to be cut up while still in the shaft.
The M7 class began to be phased out in the 1950s as part of British Railway’s Modernisation Plan, by which time they were mostly being used on branch lines.
