[edit] A successful french duplex
In France the duplex type was made famous by the ten 2-4-6-2 (151 A) compound locomotives built in 1932 for the Paris-Lyons-Marseilles company (PLM) to haul heavy goods-trains on the 1/125 gradient between Les Laumes and Dijon.The performance was so good the company wanted to order more engines but the nationalization of the railways (1938) stopped all projects. These duplex engines were fitted with Lenz-Dabeg rotary-cam valve-motion and soon with double exhaust.The LP cylinders drove the first coupled axe.The driving wheels had a diameter of 1.50m (4'11").The highest permissible speed was 53mph. In a test,December 19,1933,the engine developped slightly more than 3000HP at the drawbar on a distance of 37 miles at a speed of at least 46mph and that without beeing overworked.In ordinary service the engines could haul 1375 US tons sustaining a speed of 31mph at the summit of the 1/125 Blaisy gradient. The 151 A were withdrawn in 1956 and scrapped.Blaisy 12:11, 20 February 2007 (UTC)82.124.196.7 10:36, 27 February 2007 (UTC)82.124.145.71 11:34, 8 March 2007 (UTC)
