24 hour ticket and delayed train

[ben2]

I often buy a 24 hour train ticket (4 zones in Zürich).  If I wait for a train that is valid with the ticket, what happens if the train is delayed?

With a multi-card, it only needs to be valid at the start of the trip. Can I use it on a train that gets delayed past the 24 hours?

With a single-24-hour ticket (must be valid until end of journey). What happens if the train is delayed after I get on (still valid), so my ticket expires before the end of my journey?

Hi @ben2 

If the train, which is normally within the validity of your ticket, is delayed, you can take that train. The best thing to do is to get a confirmation from the train crew or counter staff.

Have a nice day.
