Zurich Transport Authority - Technical facts about Be 4/6
Articulated light rail vehicles Tram 2000 III of type Be 4/6 with three-phase propulsion
In 1972 the Swiss rolling stock industry set the standard for modular light rail vehicles
with the delivery of the first Tram 2000 railcars. Since that date several generations
have entered service and proved equally popular with the public and operating personnel.
The introduction of the S-Bahn within the Zurich region greatly increased the passenger loads
on the tram network of the Zurich Transport Authority (VBZ).
To meet this increased demand and to maintain its rolling stock renewal program VBZ ordered a third batch of light rail vehicles in 1988. This third series consists of 23 single articulated railcars of type Be 4/5 and 15 motorized trailer cars designated Be 2/4.
These single cab vehicles are designed for unidirectional operation. A voltage source inverter is used as the three phase propulsion unit. Each of the motor bogies is driven by a three phase squirrel cage motor.
The vehicles of all three series can be freely operated in multiple.
The first prototype of a Tram 2000 with a new low-floor middle section was commissioned in summer 2001. Up to 50 trams will be fitted with an additional low floor section in the future.
