This is the first electric train of the world, which ran in 1879 on an exhibition on a 300 m narrow gauge line. Originally it was intended for a mine in Cottbus. 150 V DC from a central power rail, power 2.2 kW, speed 13 km/h (6 km/h with three trailers and passengers). Built by Siemens & Halske. A replica of this train is in Berlin, but this is the original.
