Fares will go up next week by as much as 10%

I’ve gleaned so far (and I’ll update when other prices have been confirmed)

single AB ticket from 3.20 to 3.50.

4 trips AB from 10.00 to 10.80

single ABC from 4.00 to 4.40


But a QQ if I have a ticket I bought at the old rate is it still valid after the increase? It’s the 4th of 4 ABC tickets that I bought for € 14.40 that I’ll use on Tuesday to go to BER
