Is my «Track 7» travelcard valid on VBZ services (i.e. trams and buses in Zurich)?

In the ZVV, Track 7 is valid from 7pm for all travel in the trains of the SBB, THURBO and SOB (South-East train). In all other vehicles (tram, bus, ship and cableway), Track 7 is not valid in the ZVV region. In the event of a ticket control, you would be considered a passenger without a valid ticket and required to pay a fee.

The seven25 travelcard (also valid from 7pm), on the other hand, is valid on all lines in the joint tariff area.
