MBTA Rapid Transit Events 2026

This file contains the arrival and departure events for rapid transit rail lines for 2026. It includes all heavy rail and light rail rapid transit lines. These events are used to calculate travel times, dwell times, and headways. Due to track circuit or other data issues, data is not guaranteed to be complete for any stop or date.

GTFS-RT 3830-3652 event_type string ARR: "STOPPED_AT" status for a trip-stop pair from GTFS-RT VehiclePosition. DEP: "IN_TRANSIT_TO" OR "INCOMING_AT" status for a trip-stop pair from GTFS-RT VehiclePosition. GTFS-RT ARR event_time datetime For ARR: earliest "STOPPED_AT" status timestamp for a trip-stop pair from GTFS-RT VehiclePosition or last arrival timestamp from GTFS-RT StopTimeUpdate if VehiclePosition value is not available as an Eastern datetime. For DEP: earliest "IN_TRANSIT_TO" OR "INCOMING_AT" status timestamp for a trip-stop pair from GTFS-RT VehiclePosition as an Eastern datetime. GTFS-RT 11/1/2023 5:24:51 AM event_time_sec int event_time in seconds after midnight. LAMP Calculated 30955 Changes to the data Rapid Transit Events data is now sourced from Lightweight Application for Measuring Performance (LAMP). To learn more about LAMP, please visit LAMP website. The data changed as follows: Trunk_route_id field is added. Direction field is added. Parent_station field is added. Stop_name field is added. Stop_id is now string format. Stop_sequence is now sync_stop_sequence, please see LAMP documentation for differences. Event_time is now datetime format. MassDOT/MBTA shall not be held liable for any errors in this data.
