The Deutsche Bahn website ([https://www.bahn.com/en/offers/passes/german-rail-pass](https://www.bahn.com/en/offers/passes/german-rail-pass)) offers travel in Italy. My question is – what train does that have to be? Can I use Trentialia lines or do they have to be DB?
Specifically thinking of taking a trip from Verona to Venice and this appears to be allowed, but I’m not certain which train I can actually take with it.
