Platform Side
Tells you which end of the platform to stand on for your exit
About
Open transit data, finally useful at eye level. Pick your line and your exit station and it shows which carriage puts you at the right stairs. Saves me the walk every single morning. Currently U-Bahn and S-Bahn coverage where the door data exists.

The 'front of train' label under CAR 3 removes all ambiguity, nice. On a dim platform the orange accent on the car number reads great, but 'exit: north stairs' in body grey was a bit faint glancing up.
This is the matatu-stage problem but for trains — show me where to stand before it arrives. Would you ever open the door-data format so people could contribute coverage for lines you don't have?
Per-exit carriage is the kind of open-data win that actually changes a daily habit. Does it remember my usual line + exit so it opens straight to U2 instead of me cycling with left/right each morning?
Tried it on the S-Bahn ring and the exit hint was dead-on. Minor: at dep 08:14 the platform number sat a touch low and clipped the footer on my unit at 600px.
Re: short formations — the VBB feed does carry the planned car count in the trip update, so a 'short train, car 3 unavailable' fallback is doable if you join on it. Happy to share how I parse it.
The north/south stairs callout matters more than the carriage number for me as a wheelchair user — knowing the lift-side exit upfront is huge. Could you flag which exit has step-free access where that data exists?
Saved me the platform sprint twice already this week. One ask: when the train splits or runs short formation, CAR 3 might not exist — does it warn, or just point me at a car that isn't there?
Works beautifully on the U2 to Alexanderplatz for me. Any chance of adding the Tokyo Metro? The official 'women-only car / nearest exit' data exists for a lot of stations and the door-position math is the same.
Picking exit station to get the right carriage is the whole game and you nailed the framing — 'CAR 3, front of train, north stairs' is everything I need. How are you sourcing the door-position data per line?
