MODERN CAR LIGHTING.

Several years ago the interests I'm control OF

The popularity Of this lamp t. evidenced 10y tho
fact that in Jhe last two years more than 100

and the pateUt.es refer with pride L. the fact
that 1t Is possible To take the old lamps and
equipment and by simple alterations make them
available for the new system. Work Of this
character has been done on an extensive scaIs

the conditions ot railroad service. and it is a
matter of record that each lamp viii furnish
100 candle power illumination At a cost OF about
one cent hour.
There IS also an increasing requirement for
electric lighting on special trains. In this field
three systems have been used storage battery,
axle dynamo and dynamo in baggage car But
at best the operating cost II an electric system
IS in excess ~ the cost of lighting ears with tho
Pintscu inverted mantle lamp and the camilla
power Of the latter greatly exceeds that Of tho
electric systems. In electric equipment tho
preference. however. leans to the axle driven
dynamo. owing to the fact that the car is thco-
reticaly entirely independent Of charging sta
tons. The Safety axle driven dynamo equip
efficiency after sixteen years experience. and
the patentccs claim efficiency. reliability and
economy. That the equipments are popular IS
evidenced 10y the following recent orders: Chi

Of interest is the vapor lighting equipment. rec

been placed upon the market "A locomotive head

greatly to improve on the oil burner and still
avoid an undesirable intensity.
EquallinS the question Of car lighting in i'm.
portance is car heating system giving exactly
the heat required. irrespective of the outside
temperature. The new thermo- jet system was
constructed To meet these requirements. Tho

steam. provides for the regulation of the tenn
perature of the radlatng pipes both above and
below 2l2 degrees and at ali times lust enough

the radiating pipes. In heating another achieve
ment has been the general adoption of the 81
type of straight-pOrt coupler for transmission OF
steam from car to car. The popularity of this
coupler is best evidenced BY reference to the
fact that more than $1,000 have been sold In
the last three years
