FAQPage Schema

How do I get real-time subway arrivals for a specific NYC station?▼

Real-time subway arrivals are retrieved by querying the MTA GTFS-RT protobuf feeds for specific stations. You can ask for the next train at a given station to receive live arrival times alongside active service alerts.

Do I need an API key to check real-time bus predictions?▼

Yes, retrieving real-time bus predictions requires an optional MTA_BUS_API_KEY. Subway arrivals and service alerts function without it, but bus queries require this key for the SIRI JSON API integration.

Can I find subway lines and bus routes using NYC transit data?▼

Yes, route and stop discovery allows you to find subway lines, bus routes, and nearby stops using NYC transit data. This functionality parses the MTA GTFS-RT protobuf feeds and SIRI JSON API.

How do I check for subway delays and planned service changes?▼

Subway delays and planned service changes are provided through service alerts. Querying the GTFS-RT feeds returns active delays and service changes affecting specific subway lines and bus routes.

What data formats are used for NYC subway and bus transit information?▼

NYC subway and bus transit information is delivered using GTFS-RT protobuf feeds and SIRI JSON API formats. These data protocols provide the real-time vehicle positions, arrival predictions, and service alerts.

Does this MTA transit tool work without setting up a bus API key?▼

The MTA transit tool works for subway arrivals, service alerts, and route discovery without an MTA_BUS_API_KEY. Bus predictions are the only feature restricted until the optional key is provided.
