Show HEATING CARS BY STEAM The superintendent motive power of the New York New Haven and Hartford Hart-ford Railroad Mr John B Henney Jr has devised a system of car heating which it is said has given satisfactory results The exhaust from the Westinghouse Westing-house air pump is delivered into the ordinary or-dinary radiating pipes of the Baker system sys-tem A recent trial of the system is thus described In order to ascertain how quickly four cars can be heated by the steam from a locomotive orders had been given during the forenoon to extinguish extin-guish whatever fire there might be in the stoves Then the windows of the cars were raised and the raw March wind had an obstructed passage through the cars When the locomotive was coupled to the train connection was established between the exhaust steam pipe on the side of the locomotive and the steam pipes that extended through the several cars the old pipes in the cars being used for that experiment Despite the frigid atmosphere in the cars at the commencement of the experiment caused by these open doors and windows in thirty minutes from tho time the windows were closed and steam let on the cars were as warm as stoves could possibly have made them The train made the run to New Haven in fiftyfive minutes and the last car was kept as warm as the first It required no more steam and consequently conse-quently no more fuel than was needed to run the engine the steam used for heating having before been wasted The pipes are so arranged that in case of accident ac-cident the steam can be let out instantaneously in-stantaneously from the outside of the car thereby preventing any injury from scalding by steam Scientific American |
