One of the most detailed books ever to be written about an individual locomotive, First of the Last charts the career of the First locomotive (D400/50050) of the Last batch of British-built mixed traffic locomotives. Chapters cover the genesis of the Class 50 in prototype DP2, first-built production locomotive D400 and its introduction to traffic and the transfer of the fleet to the Western Region, refurbishment and withdrawal followed by an account of 50050's life in preservation. This 140 page paperpack will be a fine addition to any 50 fan's bookshelf.
