GAUGE FOR STEAM HEATING.(On Locomotive.) Experience has shown that it is best to carry a pressureof 40 lbs. on the train-pipe for a train of eight cars orless, and that for a greater number of cars, the pressureshould be increased five pounds for each car above is better to have a pressure higher than is needed thanone that is too low, and it is not a serious drain on thelocomotive. The amount of extra work put on a locomo-tive, by the steam heating of its train, is measured by HEATING AND LIGHTING CARS 71 the amount of water condensed by each car, and isroughly about 40 to -60 lbs. per hour per car. Care should be taken to keep the steam gauge, Figure17, in good order, and it should be tested and corrected,if necessary, at least once each season. Many cases ofreported failures of trains to heat properly are found tobe due to errors of gau^^es, the pressure actually suppliedbeing far below that indicated by the gauge. - STEAM COUPLER TROUBLES.
