ELECTRIC LIGHTING OF TRAINS
GENERAL PRINCIPLES
Introduction. This text gives to the reader a general working idea of the train-lighting problem and a knowledge of the systems employed in this country. It is intended to give train-lighting electricians a general idea of the troubles encountered with such equipments and the cause of these difficulties. It presupposes a working knowledge of electric generators, electrical circuits, and storage batteries.
Early Applications. The problem of railway train lighting is not a new one. One of the earliest applications of the incandescent lamp and the storage battery was to train lighting, but the lamps were inefficient and the equipment was bulky and costly. As early as 1881 Camille A. Faure, the inventor of the pasted storage-battery plate, was granted a patent by the French Government on a combination including a generator driven by a belt from a car axle, regulating means for the generator, a storage battery charged by the generator, and incandescent lamps furnished with current from the generator or the battery or both. The same system was granted United States letters patent on March 20, 1888. The introduction of the tungsten lamp increased the efficiency of the system and reduced its cost and size to such an extent that in the last ten years train lighting by electricity has become the standard method.
The advantages resulting from the application of electricity to railway-coach illumination are obvious. However, as they are also important, they are enumerated as follows:
1. The horrors attending any railway wreck are in themselves bad enough, but when oil or gas lamps are in use,
