They are located a few inches above the tops of
the car windows and with reference to the direction of approaching
trains the lamps in each row are carried upon the far side of the iron
columns, by which expedient the eyes of the approaching motormen are
sufficiently protected against their direct rays.
[Sidenote: _Lighting of
the Power
House_]
For the general illumination of the engine room, clusters of Nernst
lamps are supported from the roof trusses and a row of single lamps
of the same type is carried on the lower gallery about 25 feet from
the floor. This is the first power house in America to be illuminated
by these lamps. The quality of the light is unsurpassed and the
general effect of the illumination most satisfactory and agreeable to
the eye. In addition to the Nernst lamps, 16 c. p. incandescent lamps
are placed upon the engines and along the galleries in places not
conveniently reached by the general illumination. The basement also is
lighted by incandescent lamps.
[Illustration: SECONDARY DISTRIBUTING SWITCHBOARD AT PASSENGER
STATION]
For the boiler room, a row of Nernst lamps in front of the batteries
of boilers is provided, and, in addition to these, incandescent lamps
are used in the passageways around the boilers, at gauges and at water
columns. The basement of the boiler room, the pump room, the
economizer floor, coal bunkers, and coal conveyers are lighted by
incandescent lamps, while arc lamps are used around the coal tower and
dock.
