The Train WiFi Myth: Working on Trains Across Europe (What Actually Works)

The WiFi icon appeared in the menu bar. “TGV WiFi — Connected.” I opened my browser, clicked the captive portal, accepted the terms, waited thirty seconds for the spinner, and ended up on a page that would not load. I tried refreshing. Tried opening a new tab. Tried a plain HTTP address to force the portal redirect. Nothing. We were somewhere south of Lyon doing 320 km/h, and the entire 500-person train was connected to the same underprovisioned satellite uplink that was, at that moment, serving nobody adequately.

I plugged my phone in, turned on the hotspot, connected my laptop. Within ten seconds I had 47 Mbps down and 22 Mbps up from Saily’s European 5G plan.

That scene has repeated itself, in different carriages and different countries, across fourteen routes and eight countries over the last two years. The verdict is always the same: European train WiFi is a marketing feature, not a working infrastructure. It exists to put a checkbox on the seat reservation page and a sticker on the headrest. It is not there for you to upload a presentation at 200 km/h through the Rhône Valley.

This is the guide I wish I had before I started trying to work on trains across Europe. It covers what actually works, which country’s rail system comes closest to delivering on its promise, why the technology is structurally compromised, and — most importantly — the tethering setup that makes every European train journey a reliable workspace.

Why Train WiFi Is Fundamentally Broken

Before we go country-by-country, it is worth understanding why train WiFi is so consistently bad. Because it is not just neglect — there are genuine physics and infrastructure problems that even the best-funded rail operators cannot fully solve.

The Shared Uplink Problem

A modern high-speed train carries between 300 and 600 passengers. Of those, a meaningful fraction — call it 80 to 150 people at peak times — will connect to the train’s WiFi. All of those devices share a single satellite or cellular uplink with a capacity somewhere between 50 and 150 Mbps on a good day. Divide that by 100 active users and you are looking at 0.5–1.5 Mbps per person before protocol overhead. That is dial-up territory.

Some rail operators use antenna arrays that aggregate multiple cellular bands or combine satellite with trackside 4G. It helps, but it does not solve the core maths. When the train fills up, the WiFi gets slower. That is not a bug — it is a consequence of shared infrastructure with no per-user bandwidth guarantee.

Tunnels Kill Everything

Europe’s rail network runs through hundreds of tunnels. Most of them are communication dead zones. Satellite signals cannot penetrate rock and concrete. Cellular signals require trackside repeater infrastructure that most tunnels lack. The result is periodic, total disconnection every time the train goes underground.

On some routes — the Swiss Gotthard, the French TGV Alpine crossings, the Spanish high-speed tunnels — you can lose signal for 5, 10, even 35 minutes at a stretch. On a video call, that is not a dropped connection — that is the end of the meeting.

Captive Portals Waste Everyone’s Time

Even when the underlying bandwidth is adequate, most European train WiFi systems gate access behind a captive portal login. You connect to the network, open a browser, wait for the portal redirect, enter your name or reservation number, accept the terms, and finally get handed a session cookie that lets you access the internet. This process takes between two and eight minutes. On a four-hour journey with six tunnel disconnections, you might spend thirty minutes just re-authenticating. Some portals do not re-authenticate automatically after a dropout — you have to go through the whole process again.

Speed Tests: What We Actually Measured

Here is what we recorded across the 14 routes we tested. These are median download speeds during the working portions of each journey, excluding tunnel sections.

Country	Operator	Route	Median Down	Median Up	Reliability	Captive Portal
France	SNCF/TGV	Paris → Lyon	2.1 Mbps	0.8 Mbps	Poor	Yes
France	SNCF/TGV	Paris → Bordeaux	1.4 Mbps	0.6 Mbps	Very Poor	Yes
Germany	DB ICE	Frankfurt → Berlin	8.3 Mbps	3.1 Mbps	Moderate	No
Germany	DB ICE	Munich → Hamburg	5.7 Mbps	2.2 Mbps	Moderate	No
Spain	Renfe AVE	Madrid → Barcelona	6.2 Mbps	2.8 Mbps	Moderate	Yes
Spain	Renfe	Madrid → Valencia	3.1 Mbps	1.1 Mbps	Poor	Yes
Italy	Italo	Rome → Milan	7.4 Mbps	3.4 Mbps	Moderate	No
Italy	Trenitalia	Florence → Venice	1.9 Mbps	0.7 Mbps	Very Poor	Yes
Switzerland	SBB	Zurich → Geneva	11.2 Mbps	5.8 Mbps	Good	No
Switzerland	SBB	Zurich → Lugano (Gotthard)	8.9 Mbps	4.1 Mbps	Good	No
UK	LNER	London → Edinburgh	9.1 Mbps	4.3 Mbps	Moderate	No
UK	GWR	London → Bristol	4.2 Mbps	1.8 Mbps	Poor	Yes
Netherlands	NS	Amsterdam → Rotterdam	6.8 Mbps	3.2 Mbps	Moderate	No
Sweden	SJ	Stockholm → Gothenburg	12.4 Mbps	6.1 Mbps	Good	No

“Reliability” here means the percentage of the journey where the connection was usable without interruption. Good = above 70%, Moderate = 40–70%, Poor = below 40%.

For comparison: our eSIM tethering (Saily European 5G plan) averaged 43 Mbps down and 18 Mbps up across the same routes, with blackouts only in the tunnel sections.

Country-by-Country: The Real Situation

France — TGV / SNCF: Beautiful Trains, Broken WiFi

The TGV is a genuinely spectacular train. It is punctual, comfortable, quiet, and travels at speeds that make air travel feel slow once you factor in airport time. The WiFi is embarrassingly bad.

SNCF has been promising a fix for years. In practice, the TGV WiFi system is satellite-dependent and severely bottlenecked. On the Paris–Lyon corridor — arguably the most-used business route in France — we recorded a median of 2.1 Mbps download during three separate tests. Connecting to the captive portal alone took four to six minutes each time.

The French countryside does not help. Between Paris and Bordeaux, there are long stretches with no trackside cellular infrastructure, which eliminates the cellular fallback some other rail systems use. The train’s satellite connection is all there is, and it is not enough.

Verdict for France: Tether from an eSIM. Do not even attempt to use TGV WiFi for work. Treat the captive portal login as a funny story, not a tool.

Best seats for cellular signal on TGV: Window seats on the left side (eastbound journeys) tend to have slightly better line-of-sight to towers in open terrain. First class is quieter but does not meaningfully improve signal.

Germany — DB ICE: WIFIonICE Is the Best of a Bad Bunch (Usually)

Deutsche Bahn’s WIFIonICE system is the most discussed train WiFi in Europe, and with reason — it is genuinely the most competent attempt on the network. DB has invested in trackside cellular infrastructure along its main ICE corridors, which means the connection aggregates multiple 4G/5G bands rather than relying solely on satellite.

On the Frankfurt–Berlin route, we averaged 8.3 Mbps and completed a 45-minute async video review session without a dropped connection through the urban sections. The problem starts when the ICE leaves the main corridor. Rural Saxony, parts of Lower Saxony, and the stretches of Bavaria between cities still drop to 1–2 Mbps or disconnect entirely.

The good news: WIFIonICE does not use a captive portal in the traditional sense. You connect and get internet access within about 60 seconds. Re-connecting after a tunnel is faster than on most other systems.

Verdict for Germany: ICE WiFi is usable for email, Slack, and light browsing on the main corridors. Do not plan video calls. On routes that pass through rural areas, tether instead.

The Munich–Hamburg catch: This route passes through some of the weakest coverage zones in DB’s network. Do not rely on WIFIonICE for anything time-sensitive between Nuremberg and Würzburg.

Spain — Renfe AVE: Decent on the Main Line, Useless Everywhere Else

Spain’s AVE high-speed network is impressive by European standards — the Madrid–Barcelona corridor is fast, comfortable, and the WiFi is better than most. We averaged 6.2 Mbps on that route, which is enough for email, Notion, and even light file downloads. The captive portal is clunky but at least stays connected between tunnels on the main line.

The problem is anything that is not the AVE. Renfe’s regional trains — the Cercanías, the Media Distancia services — have no usable WiFi. They are not really marketed as having it, but digital nomads who buy cheap inter-city tickets and expect connectivity are in for a surprise.

The Madrid–Valencia route, which mixes high-speed and regional infrastructure, averaged 3.1 Mbps with frequent dropouts through the Albacete plateau. The mountain passes near Cuenca are a consistent dead zone.

Verdict for Spain: AVE between Madrid and Barcelona or Seville is workable with low expectations. Everything else: bring your eSIM data.

Italy — Italo Beats Trenitalia Every Time

Italy has two high-speed rail operators on the main Rome–Milan corridor: Trenitalia (the state rail) and Italo (private operator NTV). The difference in WiFi quality between them is stark and consistent.

Italo averaged 7.4 Mbps on our Rome–Milan tests. The network uses a more modern uplink system, has no captive portal, and maintains connection through most of the journey. It is not perfect — the Apennine tunnels between Florence and Bologna kill signal for 10–12 minutes — but it recovers quickly and does not require re-authentication.

Trenitalia’s Frecciarossa service on the same route averaged 1.9 Mbps and frequently showed the WiFi icon as connected while serving no actual traffic. The captive portal system is genuinely frustrating: it times out the session after 20 minutes and requires a complete re-login sequence.

Verdict for Italy: If you have a choice, book Italo for the Florence–Rome–Milan corridor. On either operator, have your eSIM tethering ready for the Apennine crossing. Regional trains (IC, Regionale) have no meaningful WiFi — budget your eSIM data accordingly.

Switzerland — The Best Train WiFi in Europe

SBB, the Swiss Federal Railways, stands alone as the one European operator where the train WiFi is genuinely usable for work. The reason is infrastructure investment that most countries have not matched: Switzerland has installed cellular repeaters inside its major tunnels, including the 35-km Gotthard Base Tunnel — the longest railway tunnel in the world.

On the Zurich–Geneva route we averaged 11.2 Mbps with fewer than three significant dropouts over a three-hour journey. On the Zurich–Lugano route — which passes through the Gotthard — we averaged 8.9 Mbps and maintained a connection through the entire tunnel crossing, something that is impossible on any other network in Europe.

SBB does not use a captive portal. You connect and you are online. Re-authentication after a brief dropout is automatic.

The caveat: Switzerland’s geography still creates some dead zones on secondary routes — the Bernina railway through the Alps, smaller cantonal lines, and routes through narrow mountain valleys all have coverage gaps. But on the main intercity network, SBB WiFi is genuinely usable for a working day.

Verdict for Switzerland: SBB is the exception that proves the rule. Use the train WiFi and keep your eSIM as a backup for mountain routes.

United Kingdom — Varies Wildly by Operator

The UK’s fragmented rail privatisation model means there is no national train WiFi standard. Every operator builds and runs its own system, which produces wildly inconsistent results across a compact geography.

LNER (London–Edinburgh): The best UK operator for WiFi. Median 9.1 Mbps on our London–Edinburgh test, no captive portal, automatic reconnection after tunnels. LNER’s investment in aerial systems along the East Coast Main Line shows.

GWR (London–Bristol/Cardiff): Inconsistent. We averaged 4.2 Mbps but had three complete drop-outs lasting over five minutes between Reading and Bath. The tunnel just west of Bath Spa is a consistent dead zone.

Avanti West Coast (London–Manchester/Glasgow): We did not test this route, but it has the worst reputation of any UK operator for WiFi reliability. Multiple operator-published statements acknowledge ongoing problems.

UK cellular coverage advantage: The UK’s cellular network — particularly EE and Three — has strong 4G coverage along most intercity rail corridors. This means eSIM tethering is particularly effective on UK trains. You will get 20–50 Mbps in most non-tunnel sections.

Verdict for UK: Use eSIM tethering by default. Use train WiFi only if you are on LNER and only for non-critical tasks.

Netherlands — Short Routes, Adequate WiFi

The Netherlands is a small, flat country with excellent cellular coverage across its entire territory. NS (Dutch Railways) WiFi benefits from this: when the train connection struggles, cellular fallback kicks in almost immediately. We averaged 6.8 Mbps on the Amsterdam–Rotterdam route with near-zero dead zones.

The catch is that Dutch intercity journeys are short — Amsterdam to Rotterdam is 40 minutes, Amsterdam to Eindhoven is 75 minutes. You are rarely on the train long enough for connectivity to become a workflow issue. The bigger concern for nomads in the Netherlands is battery life, not bandwidth.

Verdict for Netherlands: NS WiFi is fine for Dutch routes. Tethering works equally well given the country’s strong cellular coverage.

Sweden — Good Coverage, Often Overlooked

SJ (Swedish Railways) consistently tests well, and the reason is similar to Switzerland: Sweden has invested in trackside cellular infrastructure along its main intercity corridors. The population density is low, which sounds like it would hurt coverage — but it also means fewer competing users on the train uplink.

On Stockholm–Gothenburg we averaged 12.4 Mbps — the highest single-route average in our tests — with stable connectivity through most of the 3-hour journey. The system does not use a captive portal, and reconnection after brief gaps is automatic.

Northern Sweden on slower regional trains is a different story. The cellular coverage gaps north of Sundsvall are real and significant. For journeys toward Kiruna or along the Inlandsbanan, budget eSIM data generously.

Verdict for Sweden: SJ intercity WiFi is among the best in Europe. For northern routes, tether.

The Tethering Strategy: Your Real Backup Plan

The consistent finding across all 14 routes is that eSIM tethering outperforms train WiFi in every metric that matters for work: speed, reliability, and reconnection time after tunnel dropouts.

The setup is simple. You need:

1. A phone with an active European eSIM data plan
2. The mobile hotspot feature enabled (most European eSIM plans support tethering)
3. A USB-C cable or saved WiFi hotspot credentials on your laptop

When train WiFi fails — and it will — you switch your laptop’s network to your phone hotspot. On a good 4G/5G connection outside of tunnels, you will have 20–80 Mbps. That is enough for video calls, large file transfers, and parallel cloud syncing.

Which eSIM to Use for Europe Train Travel

Saily (made by NordVPN’s parent company, Nord Security) is our default recommendation for European train travel. Their 10GB Europe plan covers 30+ countries including France, Germany, Spain, Italy, Switzerland, UK, Netherlands, and Sweden — exactly the route network we tested. The per-GB pricing is competitive, tethering is supported, and the app activation takes under two minutes.

Check Saily Europe Plans

Holafly is the better choice if you are doing a multi-week rail pass trip and do not want to count gigabytes. Their unlimited Europe plans remove all anxiety about data usage — you can tether freely without watching a counter. Coverage spans 36 countries including most of the Balkans and Eastern Europe that Saily does not include.

Get Holafly Europe Unlimited

Airalo is worth considering if your European train travel is concentrated in one or two countries where they offer regional plans with strong per-GB value. Their Europe regional plan is competitive, though check the tethering policy for your specific plan before purchasing.

Securing Your Connection: When to Use a VPN on Train WiFi

When train WiFi does work, it is a shared public network with no traffic encryption. The same captive portal system that logs you in can log your activity. Other passengers on the same network could, with basic tools, intercept unencrypted traffic.

For anything beyond casual browsing — logging into work tools, accessing a company VPN, using banking apps, checking email — you should run a personal VPN on top of the train’s WiFi connection. This encrypts your traffic from your device to the VPN server, making it unreadable to anyone on the local network.

NordVPN is our recommendation for train travel specifically because it has servers in every country we tested and connects in under five seconds. The Kill Switch feature is worth enabling on trains — it blocks all internet traffic if the VPN drops, preventing accidental exposure during the frequent reconnections that train WiFi produces.

Get NordVPN for Travel

The practical workflow on a European train: connect to train WiFi, activate NordVPN, work. If the VPN cannot connect (which usually means the underlying connection is too slow), switch to eSIM tethering instead — tethering over your own cellular data does not have the same security risks as a shared public network.

See our best VPN for digital nomads guide for a full comparison if you want to explore alternatives.

Practical Tips: Getting the Most Out of Train Work Sessions

Seat Selection Matters

Window seats beat aisle seats for cellular signal. The train carriage’s metal frame attenuates signal. Being closer to the window keeps you closer to the outside world.

First class is quieter but not faster. On most European trains, first class and second class are on the same cellular uplink. You get more space and a quieter carriage — valuable for calls — but not meaningfully better bandwidth.

Cars closer to the locomotive on some older European EMU trains have slightly better cellular signal because the locomotive cab is optimised for radio communication and the repeater hardware is co-located. On modern Velaro and AGV trains this is less of a factor.

Avoid the dining car for work. It is louder, has table turnover pressure, and the foot traffic disrupts video calls.

Power Strategy

Most ICE, TGV, AVE, and Italo trains have power outlets at every seat in second class. UK trains are inconsistent — LNER and Avanti have outlets in most carriages; GWR and CrossCountry have fewer. SBB Swiss trains have outlets at window seats in first class and at selected second-class seats.

Always carry a power bank. Tethering burns your phone’s battery faster than any other activity. A 20,000 mAh power bank gives you a full work day of tethering without anxiety about your phone dying in the last hour of a six-hour journey.

The Tunnel Workflow

Stop fighting tunnels. When you know a tunnel is coming — check the route map beforehand, the Gotthard is 35 minutes, the TGV Alpine crossings are 8–15 minutes — use it.

Tunnels are natural forced-focus intervals. No notifications, no Slack, no email. Your connection is down and there is nothing to do but write, think, or plan. Some of the best work I have produced on trains happened in tunnels, not in spite of them.

Download what you need before departure: documents, reference files, music, podcasts. Set up your IDE or writing app for offline mode. Work in bursts between tunnel sections rather than fighting for a continuous connection that will never be continuous.

The Gotthard Problem (and Why SBB Solved It)

The Gotthard Base Tunnel deserves a specific mention because it is the most dramatic example of why infrastructure investment matters.

The tunnel opened in 2016 and runs 57 km through the Swiss Alps. The Swiss government and SBB invested in cellular repeater infrastructure throughout the tunnel — a project that cost significantly more than simply accepting the connectivity gap. The result is that you maintain a usable cellular and WiFi connection through the full 35-minute underground crossing.

Contrast this with the 15-km Fréjus Rail Tunnel between France and Italy, the Brenner Base Tunnel approach sections, and most of the Alpine rail tunnels in Austria: complete signal blackout, no repeaters, no coverage. The difference is not geography — it is political will and infrastructure spending.

If you are planning a rail trip through the Alps, route through Switzerland wherever possible. The Zurich–Lugano–Milan corridor via the Gotthard is worth the slightly longer journey time for the connectivity alone.

Pros and Cons of Working on European Trains

The Real Value of Train Work: Forced Focus

Here is the honest reflection after two years of taking trains as a workspace across Europe: the best work sessions on trains happen when the internet is gone.

Not slow. Not intermittent. Gone. When you exit Amsterdam Centraal and the Dutch cellular coverage transitions to something patchier in the Belgian Ardennes. When the ICE drops into a long Saxon tunnel and your browser just stops. When the TGV hits the gap between two coverage zones in the Auvergne and you stare at a spinning progress indicator long enough to close the tab and open a blank document instead.

Train travel creates a container. You are in a seat, going somewhere, for a fixed period of time. Nobody expects you to be immediately available. The motion and the scenery provide the low-grade stimulation that stops a blank document from feeling threatening. The enforced disconnection removes the option of checking things that do not need checking.

The digital nomad internet anxiety — the constant background worry about speeds and uploads and connection quality — melts away when there is no connection to worry about. You write. You plan. You think through problems that have been deferred because the internet was always available to distract you from thinking them through.

Bring your eSIM. Use it when you need it. But the days I remember most productively from European train travel are not the ones where I hit 40 Mbps through Switzerland. They are the ones where the TGV disappeared into the Massif Central and I had nothing to do but work.

Frequently Asked Questions

Does train WiFi work in France?

SNCF and TGV train WiFi is unreliable and not suitable for work. The network connects in stations and major population centres, but drops repeatedly through the countryside and in tunnels. Speeds average 1–3 Mbps when it connects, making video calls impossible and file uploads frustrating. Tethering via a European eSIM (Saily or Holafly) is consistently faster and more reliable on French high-speed rail routes.

Does train WiFi work in Germany?

Deutsche Bahn's WIFIonICE service is one of the better train WiFi systems in Europe, but it still fails regularly in rural stretches between cities and in the many tunnels on ICE routes. It works well enough for light browsing between Frankfurt and Berlin, but do not rely on it for calls or large uploads. Tethering off a German eSIM is the safer choice for mission-critical work.

Does train WiFi work in Switzerland?

SBB (Swiss Federal Railways) has the best train WiFi in Europe, largely because Switzerland has invested in tunnel repeaters — even the 35-km Gotthard Base Tunnel maintains signal. Speeds are 5–15 Mbps on good days. For casual browsing and email, SBB WiFi is usable. For video calls and file transfers, a Saily or Airalo European eSIM is still the more reliable option.

Does train WiFi work in the UK?

UK train WiFi quality varies wildly by operator. LNER (London–Edinburgh) has the most reliable service. GWR and CrossCountry are inconsistent. Avanti (London–Manchester) is notoriously unreliable. Speeds average 2–8 Mbps when connected. UK cellular coverage from EE and O2 is strong on most intercity routes, making eSIM tethering a better bet than relying on the train's hotspot.

Does train WiFi work in Italy?

Italo (NTV) has noticeably better WiFi than Trenitalia on comparable routes. Italo's high-speed network averages 3–8 Mbps between Rome and Milan on a good connection. Trenitalia WiFi is unreliable and frequently disconnects. On regional trains in Italy, do not expect WiFi at all. For reliable internet in Italy by train, an eSIM with an Italian or European data plan is the practical choice.

Does train WiFi work in Spain?

Renfe's AVE high-speed network offers WiFi that is decent for its class — 3–10 Mbps on the Madrid–Barcelona corridor. Regional and Cercanías trains have no reliable WiFi. Coverage drops in the mountain passes and longer tunnels between cities. For important work, tether from a European eSIM rather than trusting the captive-portal connection.

Is it possible to have video calls on a European train?

Video calls on train WiFi are generally not viable. The shared bandwidth, intermittent connections, and tunnel blackouts create too much instability for sustained video. The best approach is to tether your laptop to your phone's eSIM data and find a window seat away from other passengers for audio. Use a wired headset to avoid the background noise of the carriage. Calls under 30 minutes on a long intercity route are feasible if you accept occasional drops.

What is the best eSIM for Europe train travel?

Saily and Holafly are both excellent for Europe train travel. Saily's Europe plans start at around $6.99 for 3GB and cover 30+ European countries with 4G/5G data — ideal for tethering when train WiFi fails. Holafly offers unlimited data plans for Europe (around $27 for 30 days) which removes any anxiety about burning through data during a long train day. Airalo's Europe regional plans are another strong option with competitive per-GB pricing.
