Trolleybuses in St. Gallen


The St. Gallen trolleybus system forms part of the public transport network of St. Gallen, the capital city of the canton of St. Gallen, Switzerland.
Opened in 1950, the system is currently operated by . , it consists of a cross-city line and three radial lines, all of which meet at St. Gallen railway station, and has a total route length of.

History

In the 1950s, the trolleybus system gradually replaced the. The last tram ran on 30 September 1957. The individual trolleybus line sections went into service as follows:
18 July 1950Bahnhof–RiethüsliLine 5Tramway replacement
15 November 1950Bahnhof–HeiligkreuzLine 3Tramway replacement
1 October 1957Stocken–Erlachstrasse–Bahnhof–NeudorfLine 1Tramway replacement
1968Neudorf–StephanshornLine 1New connection
1970Bahnhof–RotmontenLine 5Motorbus replacement

Lines

The present system is made up of the following lines:
1Winkeln–Erlachstrasse–Bahnhof–Neudorf–StephanshornBusiness days at 12-minute intervalsOperated by seven vehicle runs
3Bahnhof–HeiligkreuzBusiness days at 7.5-minute intervalsOperated by four vehicle runs
4Wolfganghof–Erlachstrasse–Bahnhof–Neudorf–GuggeienBusiness days at 12-minute intervalsOperated by four vehicle runs
5Riethüsli–Bahnhof–RotmontenBusiness days at 10-minute intervalsOperated by four vehicle runs

To this day, the Trogenerbahn runs through the inner city between the station and Brühltor on the rails of the former tramway, and thus parallel to the trolleybuses. The two modes of transport still share a common electrical substation. In the relevant section of the common route, the overhead wire voltage is only 600 V DC, as is the rest of the trolleybus system. By contrast, the remainder of the Trogenerbahn route was energised at 1,000 V DC. It now forms part of the Appenzell–St. Gallen–Trogen railway and the section that was energised at 1,000 V DC, is now energised at 1,500 V DC.
In Riethüsli, the terminus of Line 5, there is an interchange station for changing between the trolleybus system and the electrically operated Appenzell–St. Gallen–Trogen railway. Before the opening of the Ruckhalde Tunnel and rerouting of the line in 2018, the two systems used common overhead catenary poles at that station and suspension wires for about, but were electrically isolated from each other.
Line 4 has existed only since 9 December 2007. Previously, line 1 had had three different termini from 1991, and four from 1996.

Fleet

Retired fleet

The original group numbered 101–118, the fleet that opened the system in 1950, were rebodied by Hess between 1968 and 1975 and fitted with a new backup battery. They were simultaneously renumbered as fleet nos. 131–148, but not in the same sequence. Trailer operations ended either in 1991 or in March 1992.

Disposal abroad

A total of 25 trolleybuses are currently available for use on the St. Gallen system; a maximum of 21 are required simultaneously. The present fleet comprises 17 articulated buses and eight bi-articulated buses, all of which are of low-floor design:

Fleet no. 155, which was originally a single-articulated, high-floor trolleybus, is an exceptional vehicle. Fourteen years after its entry into service, it was lengthened into a bi-articulated vehicle, by the addition of a second, low-floor, trailing segment. Simultaneously, its designation was changed from BGT 5-25 to BGGT 5-25.
Originally it was planned to carry out a similar conversion to eight or nine other vehicles of this type. However, due to technical problems with the prototype, it was decided instead to purchase the seven brand-new bi-articulated trolleybuses, nos. 188 to 194.
The bi-articulated vehicles provide a large proportion of the services on lines 1 and 4, although no. 155 runs solely on line 1. By contrast, only normal articulated trolleybuses are used on lines 3 and 5, except on one occasion when bi-articulated vehicles were used on line 3 during a special exhibition.
