Short answer
Start with one connected region and one logical direction. Then decide bases, tickets or passes, reservations, open-jaw structure and whether an overnight train actually improves the trip.
Build the rail corridor first, not a country wish list.

Build route-first, not country-first
A multi-country rail trip becomes difficult when the destinations are chosen independently and connected only afterwards.
A stronger sequence is:
- choose one region;
- choose a logical direction;
- reduce unnecessary backtracking;
- keep the number of hotel bases under control; and
- only then compare the ticketing options for the actual route.
Corridor examples include:
- Paris → Brussels → Amsterdam
- Munich → Salzburg → Vienna
- Prague → Vienna → Budapest
- Milan → Verona → Venice
These are planning examples, not a live timetable or a guarantee that every service pattern is unchanged.
Treat transfer days as transfer days
A train journey may look easy on a map while still consuming a meaningful part of the day.
Keep these units separate:
- arrival block
- transfer day
- full sightseeing day
- departure block
A practical transfer day can still include a meal, walk or light evening plan. It should not automatically be counted as a full city day.
There is no universal “too long by train” hour threshold; weigh the transfer against the time and energy available.
Pass or point-to-point? Compare the route you actually built
Do not begin with the assumption that a rail pass is always the better answer.
First define:
- the cities you are actually visiting;
- which legs are fixed;
- how much flexibility matters; and
- which services need a separate reservation check.
Then compare the cost and restrictions of the exact options available for that itinerary.
There is no universal percentage-saving rule or pass-validity threshold in this guide.
Open-jaw structure can remove backtracking
If the route moves in one direction, arriving through one city and departing from another can reduce unnecessary return travel.
That does not mean open-jaw flights are automatically cheaper.
Compare the whole journey: flight schedules, rail direction, hotel moves, airport access and the value of the time saved.
Overnight trains are a trade-off, not an automatic upgrade
An overnight train may save a hotel night or daytime travel block, but it can also create a poor arrival day if sleep quality, luggage handling or timing does not work for your group.
Use it when the overnight movement improves the route as a whole—not simply because it looks efficient on paper.
Baggage: do not assume one Europe-wide rule
Baggage conditions need a service-specific check.
The safer rule is: check the operating company and the exact service you plan to use.
Current official examples illustrate why. Deutsche Bahn allows ordinary passenger luggage under its own carriage rules, while Eurostar publishes route-specific item and size limits and can apply an additional charge when limits are not met.
Do not assume a single Europe-wide baggage-fee rule.
Check the details for your chosen corridor
Use the corridor examples to choose a direction, then verify the actual connections.
Keep these limits in mind:
- the example corridors are not an exhaustive European rail network;
- baggage conditions vary by service;
- no fixed journey-hour cutoff works for every trip;
- rail-pass savings are not guaranteed; and
- example corridors still need live timetable checks.
Final decision
Build the trip in this order:
region → corridor → bases → transfer-day rhythm → tickets / pass → reservations → open-jaw or return structure → optional overnight train
A smaller connected route usually works better than adding another country and repairing the logistics afterwards.
