Steam Generator (railroad)
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.
Steam generators were developed when diesel locomotives started to replace steam locomotives on passenger trains. 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.
Steam generators would also be fitted to individual cars to enable them to be heated independently of any locomotive supply.
In Ireland, Córas Iompair Éireann used "heating cars" as standard and CIE diesel locomotives were not fitted with steam generators.

Famous quotes containing the words steam and/or generator:
“A steam ran small and terrible and shrill;
it was so still;
the stream ran from the oak-copse
and returned and ran
back into shadow.”
—Hilda Doolittle (1886–1961)
“He admired the terrible recreative power of his memory. It was only with the weakening of this generator whose fecundity diminishes with age that he could hope for his torture to be appeased. But it appeared that the power to make him suffer of one of Odette’s statements seemed exhausted, then one of these statements on which Swann’s spirit had until then not dwelled, an almost new word relayed the others and struck him with new vigor.”
—Marcel Proust (1871–1922)
