shift started. Only on small railways, or on narrow-gauge locomotives with smaller and faster-warming boilers, was the fire lit by the fireman. Whoever was responsible for fire-starting would clear the ash from the firebox ashpan prior to lighting the fire, adding water to the engine's boiler, making sure there is a proper supply of fuel for the engine aboard before starting journeys, starting the fire, raising or banking the fire as appropriate for the amount of power needed along particular parts of the route, and performing other tasks for maintaining the locomotive according to the orders of the engineer (US) or driver (UK). The engine itself was cleaned by an engine cleaner instead of the fireman. Some firemen served these duties as a form of apprenticeship, aspiring to be locomotive engineers themselves. In the present day, the position of fireman still exists on the Union Pacific Railroad, but it refers to an engineer in training. The fireman may operate the locomotive under the direct supervision of the engineer. When the fireman is not operating the locomotive, the fireman assists the engineer and monitors the controls. Mechanical stoker A mechanical stoker is a device which feeds coal into the firebox of a boiler. It is standard equipment on large stationary boilers and was also fitted to large steam locomotives to ease the burden of the fireman. The locomotive type has a screw conveyor (driven by an auxiliary steam engine) which feeds the coal into the firebox. The coal is then distributed across the grate by steam jets, controlled by the fireman. Power stations usually use pulverized coal-fired boilers. Notable stokers Vladimir Lenin, disguised as Konstantin Petrovich Ivanov, escaped to Finland in 1917 on train 293 from Udelnaya Station. Hugo Jalava, a co-conspirator and the train's driver, helped to further conceal Lenin by having him work as his stoker. Jalava later recalled that Lenin shovelled with gusto as he fed the engine, making the train run fast. There were approximately 176 stokers on board the coal-fed ocean liner RMS Titanic. During the sinking of the ship, these men disregarded their own safety and stayed below deck to keep the steam-driven electric generators running for the radiotelegraph, lighting, and water pumps. Only 48 of them survived. Simeon T. Webb was the fireman on the Cannonball Express when it was destroyed in the legendary wreck that killed engineer Casey Jones. Jones's last words were
