The Serfaus U-Bahn (formerly: Dorfbahn Serfaus ) is a driverless, rope-powered air-cushion lift in the Austrian municipality of Serfaus . It is the third smallest underground after the Swiss Mühleggbahn and the Turkish Tünel (although all three are not underground trains in the traditional sense) and the highest air-cushion railway in the world. The train is classified in the category of people mover , but has some features of a subway, such as the separation from individual traffic and the route that runs continuously in a tunnel . From a legal point of view, the Serfaus U-Bahn is a funicular . The subway is operated by the Komperdell GmbH cable car .
route
The railway runs under the Dorfbahnstraße in a tunnel, this was built using an open construction method . It connects the parking lot on the valley-side, eastern edge of the village with the valley station of the cable cars and the ski lifts of the Komperdell ski area on the mountain-side, western edge of the village. The route length is 1.3 kilometers, the smallest curve radius 300 meters. With a maximum incline of 5.35 percent, a total height difference of 20.1 meters is overcome.
Stations
There are four barrier-free and pram-friendly stops: parking lot , church , center (formerly Raika ) and cable car . For safety reasons, there are additional platform screen doors between the platform and the entrance . The cable car station has nine doors, car park eight, center and church six each. Because the vehicle has nine doors, the outer doors do not open at the latter stops. This is indicated by a display and light strips on each door by means of a green or red glowing signal. The stations were also staged with different themes; The church station deals with the cultural and tourism history of Serfaus, the center with the village's club life and the cable car with the cable car technology and the development of the Serfaus subway.
business
The subway operates between 7.45 a.m. and 6.45 p.m. during the winter and summer seasons and the journey takes between nine and eleven minutes. This is due to the speed of travel and the travel program - the intermediate stations center and church are sometimes only served in the respective main load direction, i.e. in the morning towards the cable car, in the afternoon towards the parking lot. The train travels in the opposite direction without stopping. Longer drives are used on special occasions. The journey is free, with an average of 1.5 million passengers per year .
technology
A synchronous motor with 1.5 MW in the end station of the cable car on the mountain side drives the 38 millimeter thick pull rope. This runs behind the guide rail, which is attached to the tunnel wall near the floor. The railway has no rails ; Instead, the train slides around a tenth of a millimeter above the ground on an air cushion . Three compressors per car supply 82 air cushions with a pressure of 0.2 bar . The electrical systems in the cabins such as interior lighting, compressors and door drives are supplied by an overhead line . This is attached to the tunnel ceiling and carries 950 volts alternating current .
The subway vehicle consists of three firmly coupled cars, each with three entrances, which are continuous via bellows . The train is 45.2 meters long, 2.35 meters wide and 3.19 meters high. The maximum capacity is 440 people. In the stations, the platforms are separated from the actual tunnel by a partition wall and are provided with platform screen doors. These open and close at the same time as the cabin doors. The fully automatic operation is controlled from the operations control center in the cable car station . The maximum speed is 40 km / h and a maximum of 3,000 people can be transported per hour. The nominal drive power is 1.5 megawatts, the power requirement of the vehicle at full load is 51 kilowatts. The running equipment was built by Sigma Composite, while the new cable car technology for the subway comes from Leitner GmbH.
history
prehistory
Because too many people tended to with their private car and the last few kilometers to the stopover, the cable car valley stations pull up, although the Serfaus village road is a dead end , it was especially during the winter season again and again to traffic congestion , the quality of life for residents and tourists severely impaired. In 1970 the local council decided to close the village road to private traffic and to build a large car park at the entrance to the village. From then on, ski tourists were transported by buses . Due to the steadily growing number of tourists, these “ski buses” soon reached their capacity limits.
Serfaus village railway
In 1983 the engineering office Lässer-Feizlmayr (ILF) from Innsbruck received the order to work out an alternative transport concept. An underground air-cushion suspension railway from the parking lot to the valley station of the mountain railways was proposed. In December 1983 the local council approved the project and construction work began in July 1984. On December 14, 1985, the Serfaus village railway (then called) went into operation . The official opening took place on January 16, 1986.
Reconstruction, Serfaus subway
As early as 2007, a discussion developed that the Serfaus subway had to be modernized in order to cope with the growing number of visitors and to meet new technical requirements. Plans for the renewal or renovation of the Serfaus subway were presented to the public on October 17, 2016.
On April 24, 2017, the groundbreaking ceremony for the first construction phase of the renovation took place at the church station . In the course of the total of three construction phases, all stations were modernized and made barrier-free and suitable for prams, a new wagon train was installed and the transport capacity increased.
In July 2019 the railway was put back into full operation, on September 8, 2019 the now named Serfaus underground railway was officially opened.
incident
On the afternoon of September 4, 2019, there was an earth fault , whereupon the railway automatically performed an emergency stop. Passengers fell in the car, 13 were slightly injured.
