 A new form of urban transport, the electric tram, arrived in Rotterdam in 1904, with the creation of the new RETM ("Rotterdamsche Electrische Tramweg Maatschappij").On 18 September 1905, the RETM began operating the first electric tram line in Rotterdam, line 1 (Honingerdijk – Beurs – Park).The current to power the line was supplied from a temporary generator.
