System map

The light rail system was gradually opened between 1976 and 2008 by relocating the inner-city tram tracks in underground tunnels and opening new express tram routes that are independent of road traffic (e.g. Kirchderne – Grevel). It operates on 75.0 kilometres (46.6 mi) of route (of which 20.5 kilometres (12.7 mi) are underground in tunnels, with the other 54.5 kilometres (33.9 mi) being above-ground in dedicated rights-of-way).[2] It has 23 underground stations and 59 on the surface.[1]

Network

The system has eight Stadtbahn lines:[3]

Line Route
U41 Dortmund-Hörde – Lünen–Brambauer
U42 Hombruch – Grevel
U43 Dorstfeld – Wickede

U45 Westfalenhallen – Dortmund Hbf – (Fredenbaum)
U46 Westfalenhallen – Brunnenstraße
U47 Westerfilde – Aplerbeck
