Tube, Train, Tram, and Car; or, Up-to-date locomotion

The author surveys early twentieth-century developments in electrical traction, explaining how electric power is generated and distributed for locomotion and describing systems such as underground and tube railways, overhead lines, municipal and rural tram and light-rail networks, and battery or accumulator-driven motor vehicles. Practical details include powerhouses, dynamos, units of electrical measure, and rolling-stock arrangements, while case studies of pioneering lines illustrate operational variety. The narrative anticipates broader social and economic effects of widespread electrification, including expanded suburban access, cleaner streets, and new modes of freight and passenger transport.
