I am from Germany and I would like to travel by train from Bremen to Lyon and back from Lyon to Bremen to visit a friend. The date I plan to travel to Lyon is May 17th, and the day I want to return from Lyon to Bremen is May 21st or alternatively May 22nd. I have checked train connections on the website of Deutsche Bahn, but the fares are significantly more expensive than using the Interrail Global Pass. Therefore, I would like to use the Global Pass with the "4 days in a month" option during my travels. However, I am uncertain about which connections I am allowed to take. Can I take the TGW, the IC, and the ICE trains with the Interrail Global Pass? I will only be traveling on two days (instead of four days as paid for in the pass) with a few changeovers on both trips. With these information provided, is it possible for me to purchase the interrail global pass “4 days in a month” for around 230 Euros?
I would be really thankful for help Thanks in advance!
