Where will your coach
actually stop?

Other apps tell you your coach number. This tells you where to stand — and whether you have time to walk there.

We show you how fresh this is. Rake compositions change late — a number with no timestamp is the reason people end up at the wrong end of the platform.

Where are you now?

Tap the painted zone letter nearest to you. It's on the platform floor and on the pillars.

We don't use GPS. Under the Dadar platform roof it's accurate to about 10 metres — enough to know you're at the station, useless for knowing which end you're at.

Can't see a letter?

Pick the landmark you're standing next to instead — the staircase, the water booth, the vada pav stall, the book stall.

No smartphone? Same answer.

Railways already sends PNR and platform SMS. This is one extra line on a message that is already going out.

PNR 8624517390 · 12809 CSMT–HOWRAH MAIL · DADAR PF 5 · Coach S7 Berth 34.

Stand at ZONE B (near the lift & foot-over-bridge). Zone letters are painted on the platform floor.
Why this matters

A smartphone-only feature is worth nothing to the traveller most likely to panic — first-time, elderly, or on a feature phone. The SMS line and the painted letters carry the whole idea without an app.

The physical layer

Eight large letters painted along every platform, repeated on the pillars.

What it costs

Paint and a stencil. No screens, no sensors, no power, no network. Coach Guidance Display Boards already exist at big stations — this is the version that works at the other 7,000.

What it unlocks

A shared vocabulary. Announcements, display boards, the app, the SMS and a stranger giving directions can all say the same word: "Zone B". Today each of them describes the same place differently, or not at all.
