Furness Railway D5 Class

The Furness Railway 1 class 0-6-0, classified D5 by Bob Rush, was a class of nineteen 0-6-0 steam locomotives designed by W. F. Pettigrew and built between 1913 and 1920, four by Kitson and Company and fifteen by the North British Locomotive Company. It was the final development of the Furness Railway six-coupled goods engine and used the standardised wheels of 1.41 metres diameter and 18 by 26 inch cylinders of which Pettigrew had become a great proponent, with boiler pressure raised to 170 pounds per square inch from the 150 of the D3 and 160 of the D4. Only four were built at first; during World War I a further fifteen were added, with boilers six inches longer that made them more capable but two tonnes heavier. As the largest and most powerful of the mineral engines on the railway, they were fitted with vacuum brakes and steam heating so that they could work excursions and railtours. All nineteen were assigned London, Midland and Scottish Railway numbers, but only six survived to carry a British Railways number, the only ex-Furness locomotives to do so. Withdrawals began in 1930, the last three went in 1957 and none was preserved.
