. The street railway review . N OF ENllINE ROOM KLOOK. cylinders of the air compressors, to the condensers, and to the en-gine cylinders. Dynamo oil is handled from an independent tank in the oil house,from wliicli it is forced by air pressure to a faucet conveniently lo-cated in the engine room where it is fed by liand to the oil cupsof the dynamos as required. When in case of fire or other accident, it is desired to force theoil from the supplemenlal tanks and out of tlic engine room, andunt of the power house building, it is merely necessary to open oneset of three valves as indicated. By opening these three valves, com-oresscd air is admitted at the top of each of the supplemental tanks.■*nd in addition the way is opened for the oil from each tank toflow back to the oil house through the main supply pipes, it beingborne in mind that these pipes are normally empty. It will beunderstood, therefore, that when these emergency valves are openedthe air forces all the oil that may be contained in the oiling .system.

Compressed air for the oiling system is secured from three West-inghouse steam driven air brake compressors, mounted on the wallnear the oil controlling board. Air is provided at 90 lb. pressure,but this is reduced to 20 lb. pressure for use in the oiling system. As installed in this plant, it requires about 17 barrels of oil to fillthe entire system, but there is never over S barrels of oil withinthe engine room at any one time. The oil pipes throughout are of brass with the exception of the main return drip pipe to the filler,this being iron. Condensers.
