Leader Class Train Model

from wiki:“The Leader was a class of experimental 0-6-0+0-6-0T steam locomotive, produced in the United Kingdom to the design of the innovative engineer Oliver Bulleid. The Leader was an attempt to extend the life of steam traction by eliminating many of the operational drawbacks associated with existing steam locomotives. It was intended as a replacement for the ageing fleet of M7 class tank engines still in operation on the Southern Railway (SR). Design work began in 1946, and development continued after the nationalization of the railways in 1948, under the auspices of British Railways (BR).” Boost MeThe leader calss is probably one of my favorite trains, if you like it as well, consider giving a boost!
