Slow travel challenge: You have an Interrail/Eurail global pass for fifteen consecutive days. How many countries can you do only using trains without mandatory reservation or walking?

@partim How about: Amsterdam ๐Ÿ‡ณ๐Ÿ‡ฑ - Bruxelles/Brussel ๐Ÿ‡ง๐Ÿ‡ช - Luxembourg ๐Ÿ‡ฑ๐Ÿ‡บ - Metz ๐Ÿ‡ซ๐Ÿ‡ท - Strasbourg - Basel ๐Ÿ‡จ๐Ÿ‡ญ - Domodossola ๐Ÿ‡ฎ๐Ÿ‡น - Locarno (๐Ÿ‡จ๐Ÿ‡ญ) - Zรผrich - (Liechtenstein ๐Ÿ‡ฑ๐Ÿ‡ฎ ) - Feldkirch ๐Ÿ‡ฆ๐Ÿ‡น - (Korridorstrecke ๐Ÿ‡ฉ๐Ÿ‡ช) - Wien - Hegyeshalom ๐Ÿ‡ญ๐Ÿ‡บ - Bratislava ๐Ÿ‡ธ๐Ÿ‡ฐ - Bล™eclav ๐Ÿ‡จ๐Ÿ‡ฟ - Ostrava - Cieszyn ๐Ÿ‡ต๐Ÿ‡ฑ ?

Not only "slow" travel but all possible without mandatory reservations.

@wrzlbrnft Skip your first dip into Italy and instead go
sourh from Innsbruck and then to Trieste and add in Slovenia?
@partim I actually don't know if there is a non-reservation way from Trieste to Slovenia. Maybe via Gorizia - Nova Gorica (and maybe only this year)?
@wrzlbrnft @partim There appear to be two non-reservation REโ€™s each day at least in the other direction.
@patrick @partim I'm not sure, but I heard something about these trains only running from Villa Opicina, not from Trieste. Maybe @vorortanleiter knows more about that?
@wrzlbrnft @patrick @partim @vorortanleiter the coolest way to get from trieste to austria is gorizia/nova gorica-jesenice-villach ๐Ÿ™‚
