what is it?
Locomotive Seguin is the first steam locomotive to use a tubular boiler, a groundbreaking invention that multiplied the developed power by sixfold. Boiling is achieved by circulating the combustion gases in multiple 'fire tubes' passing through the heating body, significantly increasing the thermal exchange surface and efficiency. The boiler produced 1,200 kg (2,600 lb) of steam per hour instead of 300 kg (660 lb), enabling the locomotive to reach a speed of 30 km/h (19 mph) instead of 16 km/h (9.9 mph).
