Rapid Transit Events data is now sourced from Lightweight Application for Measuring Performance (LAMP). To learn more about LAMP, please visit LAMP website.This file contains the arrival and departure events for rapid transit lines for 2024. 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. Data Dictionary:

PRA and PRD events occur when the Performance system is relatively sure that a train actually made the indicated movement at the indicated station, but the system did not observe an "actual" event from the realtime system. In that case, we use the last available prediction for the given event as a reasonable proxy. We often lack actual ARR events at terminals because the realtime system is designed for tracking trains that passengers want to board, not necessarily trains that have already arrived at a terminal station. The instant a train arrives at a terminal station (e.g. arriving northbound at Oak Grove), the MBTA-performance system may no longer be able to track its location. In some cases, we are not able to fill in a PRA event at all, so some types of analysis are less accurate at terminals.

For each route, day, and peak/offpeak time range, this file provides numerators separate from denominators, for flexibility in combining routes, peak/offpeak, before calculating reliability metrics. It is ONLY valid to aggregate numerator and denominator values within a single mode_type. If you attempt to aggregate Reliability performance between Bus and Commuter Rail, for example, you will NOT get meaningful results. For definitions of the metrics, see the MBTA Performance Dashboard (high-level definitions) and the MBTA Service Delivery Policy (detailed definitions). Due to track circuit or other data issues, data is not guaranteed to be complete for any stop or date.Note:- on peak_offpeak_ind: rows labeled PEAK will only appear for weekdays.- contracted bus routes (i.e 712/713) are not included. - for the Commuter Rail lines with branches, the reliability metric is included for each branch.Due to data collection issues, the following dates and/or lines are missing from this data set:Oct 10-11, 2015June 1-3, 2018MassDOT/MBTA shall not be held liable for any errors in this data.

This file contains the headways, or time between the departure time of the current trip and the departure time of the previous trip from the same stop, for rapid transit vehicles. It includes all heavy rail and light rail rapid transit lines. For Red and Green lines, both trunk (e.g. all Green line trains) and branch (e.g. Green-B trains) headways are included. For lines without branches (e.g. Blue line), branch route ID and branch headway will be NULL. Due to track circuit or other data issues, data is not guaranteed to be complete for any stop or date.

Property of “Headway”. Expressed in "seconds after midnight." The time associated with the departure event of current vehicle.
Integer
46411
headway_time_sec
Property of “Headway”. Difference between start_time_sec and end_time_sec. The actual headway between two trains with the same destination, in seconds. Red line trunk stops will have two headways for the same southbound train: one dependent on the destination and one independent of the destination.
Integer
648
destination
Property of “Headway”. Intended destination for the vehicle.

IMPORTANT: This link is no longer updated. To access MBTA Rapid Transit Events 2024 data, please go to MBTA Rapid Transit Events 2024. Rapid Transit Events data is now sourced from Lightweight Application for Measuring Performance (LAMP). To learn more about LAMP, please visit LAMP website.This file contains the arrival and departure events for rapid transit lines for 2024. 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. Data Dictionary:

Human-readable, publicly visible identifier for the vehicle.String3830-3652event_typeThe type of event: ‘ARR’ for arrival, ‘DEP’ for departure, ‘PRA’ for predicted arrival, and ‘PRD’ for predicted departure. PRA and PRD events occur when the Performance system is relatively sure that a train actually made the indicated movement at the indicated station, but the system did not observe an "actual" event from the realtime system. In that case, we use the last available prediction for the given event as a reasonable proxy. We often lack actual ARR events at terminals because the realtime system is designed for tracking trains that passengers want to board, not necessarily trains that have already arrived at a terminal station. The instant a train arrives at a terminal station (e.g. arriving northbound at Oak Grove), the MBTA-performance system may no longer be able to track its location. In some cases, we are not able to fill in a PRA event at all, so some types of analysis are less accurate at terminals. Depending on your objectives, you may wish to use the second-to-last station as a proxyStringDEPevent_timeThe time of the event, in epoch time.Integer1546349755event_time_secThe time of the event, in seconds after midnight.Integer30955MassDOT/MBTA shall not be held liable for any errors in this data.
