The washing and filling pumps can be used to pump fromthe supply main directly into the hydrant line if it is de-sired to increase the water pressure in case of fire. Only thesuction connections for this purpose are shown in thediagram. It has been found that the locomotives practically furnishsufficient hot water for boiler washing purposes, and thatsufficient steam is liberated to heat all the fresh water neededfor filling boilers. Connection to the engine room exhaustmains has been made, however, in order to take advantage of the equalizing action of the constant steam supply andto overcome any difficulties which might arise through anunusual sequence of the operations of blowing, washing andfilling. The system has sufficient capacity to permit nine operationsto be carried on simultaneously. Three engines can bewashed, th
