The Metro's Countdown Screens Are Being Redrawn, and the Countdown Itself Is Being Made to Last Longer

Passengers in the Prague metro will gradually start meeting a redrawn version of the information panels at station entrances. PID, working with the Dopravní podnik, is deploying revised graphics across the network and, at selected stations, testing something less visible but more consequential: leaving the next train on the screen for longer. The transport organiser announced the change on Facebook, and both Zdopravy.cz and Expats.cz carried it on 13 September.

The screens have an official name that almost nobody uses. IPOČ stands for Informační Panel na Odbavovací Čáře — information panel at the fare-control line. That is where most of them are: at the start of the paid area, above the ticket validators, though in some stations they also sit inside the transfer concourses. Each shows the two nearest train arrivals in both directions.

What changed on the screen

The graphic revision is the part a passenger sees first. The new design has stronger contrast and a clearer marking of which line a given departure belongs to — useful mainly where two lines meet and the panel is doing more work than a simple next-train display.

What changed in the timing, and why it matters more

The second change is the interesting one, because it is a correction of an assumption rather than a redesign.

Until now the countdown to the nearest train was set conservatively. The system dropped a departure from the screen at the point where a passenger could no longer catch it while standing still on the escalator for the whole descent. That is a defensible rule and a cautious one, and it has a predictable side effect: a large proportion of passengers walk down the escalators, so for them the train vanished from the display while it was still comfortably catchable. PID says this is exactly what passengers complained about — that the countdown disappears too early.

At selected stations the organiser is now testing a longer interval, keeping the nearest service on the panel until the point at which it can no longer be reached safely without running on escalators or stairs. Expats.cz notes that PID coupled the change with the obvious caveat: the intention is not that anyone should sprint through a station to make a connection.

Neither source names the stations in the test, and PID has not said how many seconds the extension adds.

Where the panels might go next

PID also raised, without committing to anything, the possibility of putting similar screens in other places — before a passenger has even entered the underground, for example. The organiser points to some foreign metropolises already doing this.

That is worth reading as more than a throwaway. A countdown works as decision information only if it reaches you while you still have a decision to make; a screen at the fare-control line tells you whether to hurry, but a screen at street level tells you whether to go down at all, or to take the tram instead. The same logic that produced this week's timing fix — the display should stay up as long as the trip is still makeable — points fairly directly at the surface.

A twelve-year-old system

The countdown panels are not new. They began appearing in the Prague metro in 2014, when DPP tested them on line A from the beginning of September and put them into regular service there at the end of that month, before extending them to lines B and C. The system being adjusted now is therefore the original one, reaching the age at which the assumptions built into it are worth re-examining — which is essentially what has happened.
