World's first trolleybus, Berlin 1882

The Electromote was the world's first vehicle run like a trolleybus, which was first presented to the public on April 29, 1882, by its inventor Dr. Ernst Werner von Siemens in Halensee, a suburb of Berlin, Germany.[1]

The Elektromote operated from April 29 to June 13, 1882, on a 540 m (591 yard) trail-track starting at Halensee railway station, and thence to “Straße No. 5”, today's Joachim-Friedrich-Straße, and “Straße No. 13”, today's Johann-Georg-Straße, crossing the upper Kurfürstendamm at former Kurfürstenplatz.

The Electromote built by the Siemens & Halske company was a converted four-wheel landau carriage, equipped with two 2.2 kW electric motors transmitting the power using a chain drive to the rear wheels. The voltage used was 550 V DC. The electric power transmission to the coach was by a flexible cable pulling a small eight-wheeled "contact car" (Kontaktwagen) that ran along the overhead power lines; in English language use, the Kontaktwagen was later named the "trolley", giving the trolley car and trolley bus their names.

This experimental vehicle already fulfilled all the technical criteria of a typical trolleybus, after the demonstration runs closed on June 13, the test track was dismantled on June 20, 1882.
