A premetro is a tramway or light railway which includes segments built to rapid transit standards, generally as part of a process of conversion to a metro-standards railway usually by the construction of tunnels in the central city area.[1][2]
History
The first city to carry a portion of a streetcar line through the city center in a tunnel was Marseille, France, in 1893, with its Noailles subterranean station (see Marseille tramway). It was initially operated by horse-drawn wagons. The next prominent example was the Tremont Street subway (1897) in Boston, today part of the MBTA Green Line. These early tunnels were intended solely to reduce streetcar congestion on surface streets, not for later conversion to metro service.[3] Several early streetcar tunnels, including the Steinway Tunnel and East Boston Tunnel, were later converted to metro operation. However, the small loading gauge, tight curves, and steep grades of the streetcar tunnels required smaller metro cars than otherwise desirable.[3]
Second generation
The modern premetro concept Stadtbahn began in 1960s Germany, as rising traffic congestion due to auto ownership led to the construction of new transit systems. Rather than building costly metro lines immediately, some cities built only the downtown tunnels. They could be used by existing tram lines in the short term, with the intention of full metro conversion later - hence "pre-metro".[4] The idea spread to other European countries in the 1970s, especially Belgium, where such systems were explicitly named premetros.[4]
Examples
- Antwerp Pre-metro[5] in Belgium
- Brussels Pre-metro[6] in Belgium
- Charleroi Metro[7] in Belgium
- Vienna Pre-metro in Austria
- Trams in The Hague
- Nanhai Tram Line 1 in Foshan, Guangdong, China

Cities such as Frankfurt and Cologne in West Germany have further developed their tramway system by introducing a concept known as "premetro." In this system trams or light rail vehicles make extensive use of tunnels, reserve track and by utilizing folding steps these vehicles can operate through high or low stopping places.

But instead of building the entire expensive systems immediately, the Germans hit on the idea of building only the city centre tunnels at first. Intended in the long run to be extended to full undergrounds, in the short term they could be used by trams which would continue to run on the surface outside city centres. The idea spread to other European countries, especially Belgium, where it became known as pre-metro. Today Brussels, Frankfurt, Stuttgart and many other cities are filling their central business districts with construction sites to move the trains underground.

Antwerpen rail network is a typical premetro network.

The Charleroi Metro is a typical prémétro network, i.e. trams that run underground in the city centre and on viaducts or separate right-of-way through outer parts (similar to German Stadtbahn systems).
