Every London airport has a rail link, and they are not equal. This guide explains what serves each airport, where to check live first and last train times, and the overnight gap — the hours when no train runs at all, which is exactly when a lot of flights depart and land.
Key takeaways
- Heathrow: Heathrow Express, Elizabeth line and Piccadilly line.
- Gatwick: Gatwick Express, Thameslink and Southern.
- Stansted: Stansted Express. Luton: Thameslink plus the DART shuttle.
- London City: DLR. Southend: Greater Anglia.
- All have an overnight gap — and first/last times change with engineering works.
01 / WHATWhat serves each airport
Heathrow is the best connected: the Heathrow Express (fastest, to Paddington), the Elizabeth line (slower, cheaper, straight across central London) and the Piccadilly line (cheapest, slowest).
Gatwick has the Gatwick Express to Victoria, plus Thameslink and Southern services that are often better value and reach more destinations.
Stansted has the Stansted Express to Liverpool Street. Luton is served by Thameslink to Luton Airport Parkway, connected to the terminal by the DART shuttle. London City is on the DLR. Southend is served by Greater Anglia.
02 / TIMESWhere to check first and last trains
We’re not publishing a table of first and last train times, and we’d be wary of any site that does. Those times change with timetable revisions, engineering works and strikes — a table written months ago can strand you.
Check National Rail, the train operator’s own site (Heathrow Express, Gatwick Express, Stansted Express, Thameslink) or TfL for the Elizabeth, Piccadilly and DLR services — on the day you travel. Those are authoritative; a blog post isn’t.
03 / GAPThe overnight gap
Here is the thing the rail comparisons never mention: every one of these services stops overnight. There are hours — roughly the small hours of the morning — when no train runs to any London airport. And that gap overlaps precisely with early-morning departures (the 6am wave) and late-night arrivals.
So if your flight is at 6am, or you land at 1am, the train is not an option — not because it’s slow or expensive, but because it isn’t running.
04 / STRIKESAnd when it’s running, it can stop
Rail strikes and engineering closures hit airport links regularly, and they tend to be announced with enough notice to ruin a plan but not enough to fix it easily. A car doesn’t strike.
05 / RUSHXOCovering the gap
Rushxo runs 24/7 to all five London airports plus Southend, at a fixed fare with no surge — covering exactly the hours the trains don’t, and the days they’re on strike. Flight tracked, door to door, luggage handled.
FAQFrequently asked questions
What trains serve London’s airports?
Heathrow has the Heathrow Express, Elizabeth line and Piccadilly line. Gatwick has the Gatwick Express, Thameslink and Southern. Stansted has the Stansted Express, Luton is served by Thameslink plus the DART shuttle, London City is on the DLR, and Southend is served by Greater Anglia.
What are the first and last train times to the airports?
They change with timetable revisions, engineering works and strikes, so we don’t publish a table — it would go out of date and could strand you. Check National Rail, the train operator’s own site or TfL on the day you travel.
Do trains run to the airports all night?
No — every London airport rail service stops overnight. There are hours in the small morning when no train runs to any London airport, which overlaps with early departures and late arrivals.
How do I get to the airport for a 6am flight?
Before the first trains run, a pre-booked 24/7 car is effectively the only reliable option — the rail links simply aren’t running at that hour.
What happens during a rail strike?
Airport rail links are frequently affected. A pre-booked car doesn’t strike, and a fixed fare doesn’t surge on strike days when everyone switches to road transport at once — though it’s worth booking early, as demand spikes.
Is the Heathrow Express or the Elizabeth line better?
The Heathrow Express is fastest to Paddington but the priciest; the Elizabeth line is slower, cheaper and runs across central London, which can save an onward change. Neither is door-to-door.
