About yamtam - Yet Another Mass Transit All-in-One Map

Every system, one map

yamtam brings the entire NYC-area mass transit network together on a single, fast, offline-capable map — subways, LIRR, Metro-North, NJ Transit rail and buses, PATH, AirTrain JFK, the Roosevelt Island Tram, NYC Ferry, the Staten Island Ferry, MTA buses and the regional suburban bus networks of the tri-state area, plus live Citibike docks and free-floating VEO and Lime bikes and scooters.

Why you'll like it

Live arrivals Real-time countdowns for every stop, refreshed every couple of minutes — with express trains grouped with their local route and same-direction arrivals combined under one heading.
Train and bus locations Moving trains appear right on the actual track, gliding between stations, and opt-in borough toggles show buses running live in your neighborhood.
Countdown clock view An opt-in station layout with departure clocks per compass direction — the next six trains, local and express, just like the boards in the subway.
Service alerts, when they matter Alerts per station and per line, planned work shown separately, with clear start/end times — and ♿ markers pointing to accessible alternatives.
Scooters & bikes around you Zoom into a neighborhood and see docked Citibikes plus free-floating VEO and Lime bikes and scooters, right where they actually are.
Accessibility you can trust Live elevator and escalator status with outage details for every station.
Everything about the station Every entrance, bathrooms, borough, division, Wikipedia and neighborhood links — and one merged view for stations that span several stops.
Weather at a glance A live weather banner plus a 24-hour forecast and alerts for your area.
Works offline Install it as an app on your phone or desktop — the map and data are cached so you can check arrivals even without a signal.
Find your way Jump to any station by name, see your nearest stops from GPS, save HOME / WORK / favorites, and follow the built-in NYC Tour Guide.
Search by destination Type an address or landmark to find the nearest useful stations, with walk and transit directions from where you are (experimental).
Make it yours Light, dark, or system theme — and turn each transit system on or off.
Widgets & watch Any station's live arrivals as a stripped-down page you can drop into a menu-bar widget app like Glimpse or open on your watch.
From the terminal too Get the same arrivals in your shell with the yamtam command-line tool.

Arrivals on your menu bar or your wrist

Tap any station on the map and, in its View Elsewhere row, tap Widget or Watch to copy a link that shows just that station's live arrivals — no map, no menus, just countdowns.

Glimpse on the Mac. Glimpse – Webpage Widgets puts any web page in your Mac's menu bar. Grab a station's Widget link, open Glimpse, press its + button, and paste the link in — your commute's next trains are now one click from the clock. Pin a few: home station, work station, your usual weekend line.

On your watch. Grab a station's Watch link and text or AirDrop it to yourself; opening it on your Apple Watch gives you a pocket-sized arrivals board for that stop. Prefer to browse? yamtam.nyc/wt.html opens a tappable station picker, and yamtam.nyc/widget.html uses your location to show whatever station is closest.

Built for everyone, including developers

Every data file the site uses is served publicly as open JSON and GeoJSON, so you can build your own apps on top of the same live transit data. There's also a Python CLI (pip install yamtam) that mirrors the map's arrivals logic.

How yamtam pays for itself

Keeping the map free, fast, and offline-capable costs real money — live feeds from a dozen agencies, a pipeline that rebuilds every dataset around the clock, and a CDN that serves map tiles and data to every corner of the tri-state area. To offset those costs, yamtam shows a small number of Google AdSense ads. If an ad ever gets in your way, a quick dismissal gets you right back to the map.

If you'd rather skip the ads with a good feeling, you can also support yamtam on Ko-Fi. Every coffee goes straight back into keeping the platform running.

Features, fixes, comments, ideas & suggestions

yamtam is a one-person project that ships almost daily, and the best ideas come from riders. Found a bug, spotted a wrong arrival, or have a feature you wish existed? Email shawn@yamtam.nyc — every message gets a real reply, and many of the map's best features started as someone's email.

About the author

yamtam was created and is maintained by Shawn Tolidano — a lifelong New Yorker who wanted one place to see the whole metropolitan transit system, even when the subway is underground and the signal isn't.

Under the hood

yamtam is built on open data and open source: map tiles from OpenStreetMap, real-time feeds from the MTA and other agencies, and a serverless pipeline (AWS Lambda + S3 + CloudFront) that refreshes everything every couple of minutes. It's a private project on GitHub — this page itself was assembled with help from an AI assistant.
