From December 14, streetcar lines 50 and 51 will be running in Zurich: How did VBZ actually come up with these numbers? What happened to line 1 - and why is there no line 16? You can find the answers to these riddles here.

  • From December 14, there will be lines 50 and 51 in Zurich: this is how VBZ got their numbers.
  • Line 1 has been scrapped, but this number will not be reassigned for a possible comeback.

The history of Zurich's public transport system begins in 1882: back then, the Zurich Tramway Company initially operated a network almost nine kilometers long, on which the carriages were pulled by horses. It connected three then still independent municipalities to the city: Aussersihl, Enge and Riesbach.

In 1893, twelve municipalities merge with the city of Zurich. Three years later, the city founds the Städtische Strassenbahn Zürich, which absorbs both the Zürcher Strassenbahn Gesellschaft with its Rössli streetcars and the newly established Elektrische Strassenbahn Zürich. Between 1903 and 1931, further private streetcar companies were added.

At the beginning of the 20th century, the Rössli streetcars and the electric streetcars were still running in parallel. Initially they had no numbers, but were distinguished by color. From 1906, numbers were added: the "white line" was given the number 1 and served the Brunau route via Enge and the main station in the direction of Brunau Tiefenbrunnen, which had previously been served by a Rösslitram.

VBZ

From 1935, line 1 ran on the Burgwies-Kreuzplatz-Kunsthaus-Hauptbahnhof-Militärstrasse-Hardplatz route. From 1939, trolleybuses appeared in Zurich, competing with the streetcars. Electric buses have an advantage over rail vehicles, which hold up traffic, particularly on routes that are also used by many cars.

Where streetcar number 1 has remained

In 1954, the end finally came for the 1, whose number has not been reassigned since - in case the line is revived. This year also saw the introduction of a new system for the bus lines, which had previously been assigned a letter.

«Line 1, it's a horror, is still being killed off today. Nowadays they drive on rubber, whether that is better is the question.»

They were initially given numbers between 61 and 99, which was changed in the 70s to between 31 and 60. Today they are between 37 and 99. Buses that travel to the conurbation have three-digit numbers, except for line 91.

VBZ

The Zurich municipal tramway has been called Verkehrsbetriebe der Stadt Zürich since 1949 and Verkehrsbetriebe Zürich since 1978. VBZ numbers its streetcars from 1 to 20. 1 is reserved as described, line 16 is being planned. Lines 18 and 19 are technical lines, while 21 is reserved for the museum line.

But why are lines 50 and 51 being introduced now? The VBZ were looking for numbers for the interim line that would not lead to confusion. Christian Böckmann from VBZ says that blocks of numbers have been allocated for this purpose - and the 50 and 51 are "not preloaded", explains the timetable change project manager.
