How to read a train departure board (UK guide)

A UK train departure board reads left to right, one train per row: the time it's booked to leave, where it ends up, the platform, and a status that says On time, gives an expected time such as Exp 18:40, or says Delayed or Cancelled. A line underneath (a scrolling strip, on platform screens) lists every station it calls at. Get those four columns straight and you can read any board from Penzance to Inverness. The rest is knowing which bits change and which bits you can trust.

What does each column on a departure board mean?

The big concourse boards at stations like Birmingham New Street or Leeds show plenty of departures at once, one per row. Platform screens show fewer, usually the next train in full with the two after it underneath. Either way, the same few pieces of information turn up:

The booked time is the one people misread most. It's the timetable and nothing more. The status column is the live bit, and when the two disagree the status wins.

Why is the expected time different from the time on the left?

Because the left-hand time was fixed months ago, while the expected time is worked out from where the train actually is. Every time the train passes a reporting point the estimate gets recalculated. A train that's ten minutes down at Reading might claw a few back before it reaches you, so Exp times can come forward as well as slip.

Worth remembering if the board says Exp 18:47 at twenty to and you're eyeing up the coffee queue. The estimate is a forecast, and trains have a knack of making up time just as you've joined the back of a long line.

Delayed with no time at all usually means the train is being held somewhere, or the cause hasn't been sorted yet. There's a fuller list of these words, with what to do about each one, in our guide to departure board status words.

Where's the platform, and why does it appear so late?

The platform shows up once the station confirms it. At smaller stations it's normally fixed and known well in advance, since there might only be two to choose from. At some big termini (London Euston is the one everyone grumbles about) the platform often appears only shortly before departure, which is why you see crowds staring up at the screens and then a sudden surge towards the barriers.

Platforms do change, too. If yours moves, the board updates and there's usually an announcement as well. Keep half an eye on the screen until you're actually on the train, ideally in a seat.

How do you read the calling points?

The scrolling line that starts Calling at lists every stop after this one, in order, ending with the destination. Run your eye along it before you get on, especially on routes where fast and slow trains share a platform. A train to the right city that skips your station is a long way to go for a lesson.

Some trains divide part way along, with the front and back halves heading to different places. The board and the announcements say which part to sit in, so listen out for which end you need.

On platform screens the same scrolling line often names the company running the train and carries notices about disruption or engineering works. If something odd is going on, it tends to turn up there first.

What do 1st, 2nd and 3rd mean on platform screens?

They're the order of departures from that platform. 1st is the next train to leave, and 2nd and 3rd are the ones after it. The clock along the bottom shows seconds for a reason: doors lock shortly before the booked time, so arriving at 18:31:50 for an 18:32 train is cutting it very fine.

A few other things catch people out:

• The time shown is when the train leaves this station, not when it arrives anywhere.
• A train can be cut short, so the destination may change to a station before the one you expected.
• On time can still turn into Exp or Delayed while you're standing there. It's a live board.

If the three letters next to a station name puzzle you, they're explained in our guide to UK station codes.

Can you have a departure board at home?

Yes, and it reads exactly the same way. TrainTicker is an amber LED board, 320 x 80 mm, that shows the next trains from any National Rail station in Great Britain. It uses live data from Darwin, National Rail's train information system, checked every 10 seconds.

By default it shows the next train in full: time, destination, the platform once it's announced and the status, then the calling points scrolling underneath along with the last place the train called. The next two trains take their turn after it, with a clock with seconds along the bottom. Prefer the next three at a glance? Switch layouts in the dashboard. You can also tell it how long your walk to the station takes, and it hides the trains you couldn't catch anyway.
