Each engine is connected to one independent vertical,fly-wheel condenser, and these condensers are so arrangedthat their steam cylinders come up through the floor, mak-ing them easy of access. The steam pipes to the engines from the main are carriedthrough the partition wall between the engine and boilerrooms, under the engine room floor to a Stratton separatorlocated near the throttle valve on the engines. These pipeshave also long copper bends. A .safety stop valve has beenplaced between the separator and throttle. This valve willautomatically shut off the steam supply to the engines incase they should commence to race. The piping at the engines is so arranged that either.

The piping has been installed with great care and isremarkable for its absence of vibration. The main in theboiler room is carried on adjustable rollers placed on pedes-tals, bolted down to solid masonry, back of boilers, and atsuch a height above boiler room floor that all valves canbe operated by hand from the floor. The headers from the boilers to the main have long,easy bends, so as to take care of the expansion, and at thesame time retard the speed of the steam as little as possible. side, high or low, can be run independent and condensingor non-condensing, if so desired. The exhaust steam, after leaving the engines, passesthrough a heater into the condenser, or around the conden-ser into the free atmosphere, as the case may be, depend-ing upon whether the station is running condensing or non-condensing.
