A steam generator is a type of boiler used to produce steam for climate control and potable water heating in railroad passenger cars. The output of a railroad steam generator is low pressure, saturated steam that is passed through a system of pipes and conduits throughout the length of the train.
In 1903 Chicago businessman Egbert Gold introduced the "Vapor" car heating system, which used low pressure, saturated steam. The Vapor system was safe and efficient and became nearly universal in railroad applications.
When steam locomotives began to be retired from passenger runs, Gold's company, now known as the Vapor Car Heating Company, developed a compact water-tube boiler that could be fitted into the rear of a diesel locomotive's engine room. Known as the
Vapor-Clarkson steam generator
, it remained a standard railroad appliance until steam heat was phased out.
In most cases, each passenger locomotive was fitted with a steam generator and a feedwater supply tank. The steam generator used some of the locomotive's diesel fuel supply for combustion. When a steam generator-equipped locomotive was not available for a run, a so-called "heating car" fitted with one or two steam generators was inserted between the last locomotive in the consist and the rest of the train.
