A STEAM STREET RAILWAY MOTOR.

[Illustration: North Chicago Street Railroad Engine]

While in Paris, President Yerkes, of the North Chicago Street Railway

Company, purchased a noiseless steam motor, the results in

experimenting with which will be watched with great interest. The

accompanying engraving, for which we are indebted to the _Street

Railway Review_, gives a very accurate idea of the general external

appearance. The car is all steel throughout, except windows, doors and

ceiling. It is 12 ft. long, 8 ft. wide, and 9 ft. high, and weighs

about seven tons. The engines, which have 25 horse power and are of

the double cylinder pattern, are below the floor and connected

directly to the wheels. The wheels are four in number and 31 in. in

diameter. The internal appearance and general arrangement of

machinery, etc., is about that of the ordinary steam dummy. It will

run in either direction, and the exhaust steam is run through a series

of mufflers which suppress the sound, condense the steam and return

the water to the boiler, which occupies the center of the car. The

motor was built in Ghent, Belgium, and cost about $5,000, custom house

duties amounting to about $2,000 more.--_The Railway Review_.
