Their performance was so good that the company wanted to order more engines, but the nationalization of the French railways in 1938 stopped all projects. These duplex engines were fitted with Lenz-Dabeg rotary cam valve gear and soon thereafter with <a href="/wiki/Double_chimney" title="Double chimney">double chimneys</a>. The driving wheels had a diameter of 1.50 m (4 ft 11 in). The highest permissible speed was 53 mph (85 km/h). In a test on 19 December 1933, the engine developed slightly more than 3,000 hp (2,200 kW) at the <a href="/wiki/Drawbar_(haulage)" title="Drawbar (haulage)">drawbar</a> over a distance of 37 miles (60 km) and a speed of at least 46 mph (74 km/h), without being overworked. In ordinary service these engines could haul 1,375 short tons (1,228 long tons; 1,247 t), sustaining 31 mph (50 km/h) at the summit of the 0.8% Blaisy grade. After <a href="/wiki/Railway_electrification_system" class="mw-redirect" title="Railway electrification system">electrification</a> of the line, the 151A's were sent for service in northeastern France.
