Europe Train Route Planner: Passes, Prices, Best Routes

European train travel is the best in the world — until you try to plan it. The systems are national, not continental. The ticketing websites are in 30 languages. The pass that seems like a good deal costs more than individual tickets if you don't understand how it works. This guide is about making the right decisions, not listing every train in Europe.

Eurail Pass: When It Works and When It Doesn't

The Eurail Pass (for non-European residents) and Interrail Pass (for European residents) let you travel on most trains in 33 countries with a single ticket. The problem is that the pass is expensive and many high-speed trains require a paid seat reservation on top of the pass.

A 15-day continuous pass is €518 (2nd class). That's €34.50/day. If you're taking a high-speed train every day, the seat reservations add €10-35 per train — so the real cost is €45-70/day. Individual tickets for the same trains, booked 2-3 months ahead, cost €25-60. The pass is more expensive unless you're making last-minute bookings or taking 3+ trains in a day.

The pass works if:

You're traveling spontaneously and can't book ahead

You're taking 3+ trains per day (e.g., Switzerland to Italy to Austria)

You're using it in countries where no reservation is needed (Germany, Austria, Switzerland, Belgium, Netherlands)

You want the freedom to change plans without penalty

The pass doesn't work if:

You're taking 1 train per day between major cities (Paris-Lyon, Rome-Florence, Madrid-Seville)

You're booking 2+ months ahead (individual tickets are cheaper)

You're traveling in France, Spain, or Italy (high reservation fees: €10-35 per train)

You're mostly staying in one country (a single-country pass is cheaper)

The Best Train Routes in Europe

1. Paris to Lyon to Marseille (France)

TGV from Paris Gare de Lyon to Lyon Part-Dieu: 2 hours, €25-65. Lyon to Marseille: 1.5 hours, €20-45. Book on sncf-connect.com 3+ months ahead for the cheapest fares. The route follows the Rhône valley — vineyards, hills, and the occasional château. The TGV hits 320 km/h on the straight sections.

2. Rome to Florence to Bologna (Italy)

Frecciarossa from Roma Termini to Firenze SMN: 1.5 hours, €19-65. Florence to Bologna: 37 minutes, €15-45. Book on trenitalia.com or italotreno.it. The route goes through Tuscany — rolling hills, cypress trees, and hill towns on the horizons. The Frecciarossa is the most comfortable high-speed train in Europe.

3. Munich to Salzburg to Vienna (Germany-Austria)

ICE/Meridian from Munich to Salzburg: 1.5 hours, €19-40. ÖBB Railjet from Salzburg to Vienna: 2.5 hours, €19-50. No reservation needed on the Salzburg-Vienna section — just hop on. The route follows the Alps — snow-capped peaks, lakes, and the Salzkammergut region. One of the most scenic train rides in Europe.

4. Zurich to Milan through the Alps (Switzerland-Italy)

EuroCity from Zurich HB to Milano Centrale: 3.5 hours, €32-70. The route goes through the Gotthard Base Tunnel (57 km — the longest railway tunnel in the world) and emerges into the Ticino — palm trees, Italian-language signs, and Lake Lugano. Book on sbb.ch or trenitalia.com. Reservation required.

5. Berlin to Prague to Vienna (Germany-Czech-Austria)

EuroCity from Berlin Hbf to Praha hlavní nádraží: 4.5 hours, €25-50. RegioJet or ÖBB from Prague to Vienna: 4 hours, €15-45. The Berlin-Prague section follows the Elbe river through sandstone cliffs. Book on cd.cz or oebb.at. No reservation needed on the Prague-Vienna section but recommended in summer.

Overnight Trains

Overnight trains are back in Europe. ÖBB Nightjet (Austrian Railways) runs the best network — 20+ routes across Europe. You sleep in a couchette (shared 4-6 berth, €30-60) or a sleeper cabin (private 1-3 berth with washbasin, €70-150). The train saves a night of accommodation and a day of travel.

Best Nightjet routes:

Vienna to Rome (11 hours, €30-130) — wakes up in Tuscany

Zurich to Hamburg (12 hours, €30-90) — wakes up in northern Germany

Vienna to Venice (11 hours, €30-120) — wakes up on the lagoon

Munich to Paris (12 hours, €30-100) — the new direct route

Book on nightjet.com 2+ months ahead — the cheapest couchette berths sell out fast.

When the Bus Is Better

Trains are not always the best option. For these routes, the bus is faster, cheaper, or both:

Paris to London: Eurostar train is €80-250. Bus (FlixBus) is €25-50 but takes 8 hours vs 2.5 hours. Train is better here.
Munich to Budapest: Train is 6.5 hours, €40-80. Bus is 7.5 hours, €15-30. Bus is half the price.
Berlin to Warsaw: Train is 6 hours, €30-60. Bus is 7 hours, €15-25. Bus is cheaper.
Madrid to Lisbon: Train was discontinued in 2020. Bus is 7 hours, €25-40. Or fly — €40-60, 1 hour.
Any route under €20: If the train ticket costs more than €20 and the bus costs less than €15, take the bus. The comfort difference is not worth €5-10 on a 4-hour journey.

How to Book

The golden rule: book on the national railway website, not on a third-party site. Third-party sites (Trainline, Omio, RailEurope) charge booking fees and don't always show the cheapest fares.

Country	Website	Book ahead
France	sncf-connect.com	3+ months
Italy	trenitalia.com / italotreno.it	2+ months
Spain	renfe.com	2+ months
Germany	bahn.com	6 months
Switzerland	sbb.ch	3 months
Austria	oebb.at	6 months
UK	nationalrail.co.uk	3 months

High-speed trains have dynamic pricing — the earlier you book, the cheaper. A Paris-Lyon ticket is €25 if booked 3 months ahead, €110 on the day. Regional trains have fixed prices — no need to book ahead.

Practical Tips

Arrive 15 minutes early: European trains close doors 2 minutes before departure. If you're not on the platform, you miss it.
Validate regional tickets: In Italy and France, regional train tickets must be stamped in the machine on the platform before boarding. High-speed tickets don't need this.
Luggage: No weight limits on trains. No liquid rules. No security queues. This is the main advantage over flying.
Food: High-speed trains have bar cars. Regional trains don't. Bring your own — a baguette, cheese, and a bottle of wine is the proper European train picnic.
Wi-Fi: Most high-speed trains have it. It's usually terrible. Download what you need before boarding.
Seat selection: On TGV and Frecciarossa, you can choose your seat when booking. Pick a window seat on the side with the best view — for Paris-Lyon, the right side has the best views of the Rhône valley.

The One Thing

If you remember nothing else: book ahead. The difference between booking 3 months ahead and booking on the day is 3-4x the price. The European train system rewards planners and punishes the spontaneous — unless you have a rail pass, in which case it rewards the spontaneous and punishes the planner. Know which one you are before you buy.
