1. An electric locomotive
Is a locomotive powered by electricity from overhead lines, a third rail or on-board energy storage such as a battery or a supercapacitor.
Electric locomotives with on-board fueled prime movers, such as diesel engines or gas turbines, are classed as diesel-electric or gas turbine-electric and not as electric locomotives, because the electric generator/motor combination serves only as a power transmission system.
The first practical AC electric locomotive was designed by Charles Brown, then working for Oerlikon, Zürich.
In 1891, Brown had demonstrated long-distance power transmission, using three-phase AC, between a hydro-electric plant at Lauffen am Neckar and Frankfurt am Main West, a distance of 280 km.

2. Rail transport in Kenya
Railway consists of a metre-gauge network that is in poor condition and a new standard gauge railway (SGR).
Both railways connect Kenya's main port city of Mombasa to the interior, running through the national capital of Nairobi. The metre-gauge network runs to the Ugandan border, and the Mombasa–Nairobi Standard Gauge Railway, financed by a Chinese loan, reaches Suswa.
