Train travel · Switzerland

Hi, I’m planning a ski trip to Zermatt in February. I’ve heard there’s a Milan–Zermatt train that crosses the mountains in about 2h30. Is that right, and is it a scenic route?

Good evening, New to this forum, I’d love to explore these two routes mentioned in the title—train travel is a real pleasure for me. 🙂

Has anyone taken the EuroCity Zurich–Munich or the Railjet Express Zurich–Vienna? How are they in terms of crowding, delays, onboard services, and scenery along the way?

Thanks in advance!
