Europe by Train on a Budget: How to Travel Cheaply

There’s a special kind of freedom in watching the French countryside blur past a train window, coffee in hand, no security queue in sight. If you’ve been wondering how can I travel around Europe by train cheaply, you’re asking the right question at the right time — Europe’s rail network has never been better for budget travellers, with new routes, night trains making a comeback, and passes that can slash your costs. Here’s how to do it without spending a fortune.

Start with the Interrail pass (it’s better than you think)

For UK residents, the Interrail Global Pass is the foundation of cheap European train travel. The classic deal: 7 travel days within 1 month for around £250 (adult), or 10 days within 2 months for around £300. Under-27s get roughly 25% off, which makes it an absolute steal.

Is it actually good value? Do the maths on your route. A single Paris–Amsterdam–Berlin–Prague trip bought as individual tickets could easily cost £300–£400. On a pass, those same journeys cost you nothing extra (plus small reservation fees — more on those below). The pass pays for itself with 3–4 long-distance journeys. For shorter hops, point-to-point tickets are often cheaper — so plan your route first, price it both ways, then decide.

One important note: since Brexit, you still qualify for Interrail as a UK resident (it’s residency, not EU membership, that counts). And don’t confuse it with Eurail — that’s the same product sold to non-Europeans. Same trains, same pass, different name.

How can I travel around Europe by train cheaply? The booking tricks

Book direct with the train operators

Third-party sites add fees and hide the cheap fares. Book with the actual operators:

• France: SNCF Connect — the cheap Ouigo trains (France’s answer to budget airlines) start from €10–€19 if you book early.
• Germany: Deutsche Bahn — Super Sparpreis fares from €17.90 for long distances. Book 3–6 months ahead.
• Italy: Trenitalia and Italo compete aggressively — Milan to Rome from €19 is common.
• Spain: Renfe plus low-cost rivals Ouigo España and Iryo — Madrid to Barcelona from €25.
• Eurostar: Book the moment tickets release (usually 6–11 months out) for London–Paris/Brussels/Amsterdam from £39–£44 each way.

Understand seat reservations

This trips up every first-timer. In the UK, reservations are free and optional. In much of Europe, high-speed and night trains require paid reservations (€3–€35 depending on country) on top of your Interrail pass. France, Italy and Spain are the expensive ones; Germany, Austria, Switzerland and most of Eastern Europe need no reservations at all. Budget €10–€15 per reservation on average, and book them early — pass-holder quotas on popular trains (especially in summer) sell out.

Embrace the night train revival

Night trains are back in a big way, and they’re a budget traveller’s secret weapon: you save a night’s accommodation while you travel. The Vienna–Paris, Zurich–Amsterdam and Brussels–Vienna sleepers are the famous ones. A couchette (bunk in a shared compartment) runs €50–€90 — compare that to a hotel plus a daytime train ticket, and it’s a bargain. Book the moment they release (often 3–6 months out) because the cheap berths go first. ÖBB’s Nightjet site is the one to bookmark.

Slow down and go regional

Here’s the trick the pros use: regional trains are dramatically cheaper than high-speed ones and need no reservation. The German regional network (with the €58/month Deutschlandticket covering all local transport nationwide) is the ultimate example. Italy’s regionale trains, France’s TER network — they’re slower, but you see more, spend less, and can hop on and off freely. Some of my favourite travel memories are from slow trains through the Alps that cost a tenth of the high-speed alternative.

Sample cheap itineraries

The classic 2-week loop (£400–£600 all-in for transport): Eurostar to Brussels → Amsterdam → Berlin (night train or regional) → Prague → Vienna → Venice → Milan → Paris → home. Interrail pass + reservations + Eurostar.

The budget southern route: Ferry or cheap flight to northern Spain, then Ouigo/Iryo trains down through Spain, across to Portugal. Spain’s low-cost high-speed competition has made it one of the cheapest countries in Europe for fast trains.

The Alpine slow-travel week: Base yourself with a Swiss Half Fare Card or regional passes and do day trips — the Bernina Express route on regular trains costs a fraction of the panoramic-train premium.

Money-saving rules to live by

• Book early for high-speed, don’t bother for regional. Advance-purchase discounts (up to 70% off) apply to TGV, ICE, Frecciarossa etc. Regional trains have fixed prices — buy on the day.
• Travel midweek. Tuesday–Thursday trains are consistently cheaper than Friday–Sunday, just like flights at Christmas follow weekly patterns.
• Pack food. Station food is fine; onboard dining cars are a luxury tax. A €3 baguette from a French boulangerie beats a €15 train sandwich every time.
• Use the apps. Trainline’s European coverage is decent, but the operator apps (DB Navigator, SNCF Connect, Trenitalia) have the full fare range and live disruption info.
• Consider the ferry-train combo. Dover–Calais or Harwich–Hook of Holland ferries plus onward trains can undercut Eurostar, especially for groups — and you can take a car.

What about the practicalities?

A few things UK travellers forget: you’ll need your passport (obviously, but people do forget), travel insurance that covers rail disruption, and a GHIC card for healthcare across the EU. Luggage is gloriously unregulated compared to airlines — no weighing, no liquid rules, just carry what you can manage. And download offline maps and your tickets; rural stations have patchy signal.

One more tip: strike action happens (France especially). Build a buffer day into tight itineraries, and know that EU rail passenger rights entitle you to compensation for long delays — similar in spirit to flight delay compensation, though the thresholds differ.

The practical takeaway

Cheap European train travel comes down to five things: price your route against an Interrail pass before committing, book high-speed tickets direct with operators 3–6 months out, use night trains to skip hotel bills, lean on regional trains where speed doesn’t matter, and always pack your own food. Do that, and two weeks crossing Europe by rail can cost less than a week in a Spanish all-inclusive — with infinitely better stories.
