Which side do train doors open at UK stations?

Which side do the train doors open? How Railly's door-side predictor helps
You know the feeling. The train slows, you stand up, bag in hand, and realise you're on the wrong side of the carriage. Now you're pushing past three people, squeezing past a bicycle, and reaching the doors just as they start to beep. Railly's door-side predictor exists to stop that. It shows whether the doors open on the left or right at each stop, for 433 platforms across 48 stations. It won't help if the platform changes at the last minute, but for planned stops it's the difference between a smooth exit and a humiliating shuffle.
If you commute regularly, you know the moment: the train pulls into your station and you're on the wrong side. You push through a crowd of standing passengers, squeeze past someone's bag, and reach the doors just as they're closing. Knowing which side the doors will open lets you avoid that — and Railly is the only train app that tells you.
How to use it
The door-side indicator appears on the service detail page — the view you get when you tap any train on a departure board:
- Search for your train on any station departure board
- Tap the service row to see the full calling pattern
- Look at each calling point — if door-side data is available, you'll see an arrow (← left / → right) next to the platform number, with the word "Left" or "Right"
The indicator also shows how confident the prediction is:
| Confidence | What it means |
|---|---|
| High | Verified from station layout maps |
| Medium | Inferred from train direction — correct in most cases |
| Not available | This platform is not yet in the dataset |
How the prediction actually works
Railly doesn't guess. The prediction is based on a combination of platform geometry and train direction:
Side platforms — platforms that sit on one side of the tracks — are the easiest to predict. If a train is travelling northbound and the platform is on the west side of the tracks, the doors open on the left (because the driver sits on the right in the UK). The model verifies this against National Rail platform data and station layout maps.
Bay platforms — the dead-end platforms you see at terminus stations like Euston or King's Cross — are also predictable. The train arrives, reverses, and departs in the opposite direction. Railly tracks whether your stop is an arrival or a departure and shows the correct side for each.
Island platforms — a single platform between two tracks — are trickier. The door side depends on which track the train is on, which depends on the direction of travel. A northbound train might open on the left; a southbound train on the same platform opens on the right. Railly infers the direction from the timetable and applies the correct rule.
Why direction matters: In Great Britain, trains drive on the left. The driver's cab is on the right-hand side of the train. On a single-track or bidirectional line, the platform position relative to the direction of travel determines which side the doors face. This is consistent across almost all UK passenger rolling stock.
Real-world examples
Here is what the predictor looks like in practice at stations you probably use:
Euston, platform 1 — If you're arriving from Birmingham on an Avanti service, the doors open on the right. If you're departing to Manchester from the same platform, they open on the left — the train has reversed. Railly shows the correct side for each journey.
King's Cross, platform 0 — The LNER Azuma trains to Edinburgh use this platform. Departing northbound, doors open on the left because the platform sits on the west side of the tracks. This is High confidence — verified from Network Rail platform data.
Manchester Piccadilly, platform 14 — TransPennine Express services to Liverpool and the Airport depart from here. The platform is a through platform on the south side of the station. Westbound trains open on the left. Eastbound arrivals from Liverpool open on the right.
Milton Keynes Central, platform 1 — A side platform on the west side of the West Coast Main Line. Northbound trains open on the left; southbound trains open on the right.

| Chiltern Main Line | High Wycombe, Banbury, Leamington Spa, Solihull, Warwick, Warwick Parkway |
| London commuter | Watford Junction, Luton, Stratford, Enfield Town, Bush Hill Park, Highams Park |

Things to know
At terminus stations, the door side changes between arrival and departure. If you're arriving at Euston on platform 1, the doors open on one side. If you're departing from the same platform, they open on the other — because the train reverses direction. Railly accounts for this automatically, showing the correct side based on whether your calling point is an arrival or a departure. (For more on this route, see our London to Manchester guide.)
At island platforms, the door side depends on the direction of travel. A train travelling towards London may open on a different side than a train travelling away from London, even at the same platform.
Short platforms can surprise you. Some stations have short platforms that only serve the front few carriages of a longer train. For more on what facilities to expect at stations, see our station facilities guide. If you're in the rear coaches, the doors may not open at all — regardless of which side the predictor shows. This is common at rural stations on intercity routes. Listen for the guard's announcement or check the platform length before you board.
Not every station has door-side data. Coverage is growing. If your station is missing, use the feedback button on any page to request it.
The indicator is a guide, not a guarantee. In rare cases — last-minute platform changes, engineering work, or unusual routing — the doors may open on a different side than shown.
When predictions go wrong
Even High-confidence predictions can fail. Here are the edge cases we've learned about from user feedback and our own testing:
Last-minute platform changes — the most common cause of a wrong prediction. If your train switches from platform 3 to platform 12 at Euston, the door side will almost certainly change. Railly updates when the platform change reaches the Darwin data feed, but there can be a short lag.
Bi-mode trains running on diesel — some routes use bi-mode trains (electric/diesel) that can reverse at short notice. The door side prediction still holds, but the platform assignment itself may change.
Heritage or charter services — these use different rolling stock with different door configurations. The predictor is designed for modern passenger stock and may not apply.
Engineering work — when platforms are closed and trains use temporary platforms or alternative routings, the predictor may not have data for the substitute arrangement.
How to help us fill the gaps
Door-side data is a mix of automated inference and manual verification. We start with platform geometry from National Rail data, infer direction from timetable routing, and then verify against station layout maps and community reports.
If your station is missing from the predictor, or if you spot an error:
- Use the feedback button on any page — select "Door side correction" and tell us what you saw
- Include the platform number, train operator, and direction of travel — this lets us verify and update the dataset
- We verify every report against station maps and timetable data before publishing
New platforms are added weekly. The most-requested stations get priority.
