O-Train line map
The official line, stations, timetable and current service evidence are shown together. OC Transpo does not publish live train positions or arrival predictions in the public feed Otranspo receives.
The line and station dots come from the official timetable. Otranspo does not turn the timetable into a claimed live train position.

Official alerts and moderated rider observations are shown separately above. A rider sighting is evidence about its time and place, not a complete train tracker.
Service date September 19, 2026
Span and median gap are computed from today’s official GTFS stop_times. They are timetable measures, not observed headways or a frequency guarantee.
These are trip starts. For the time at your stop, open that stop’s departure board.

Route check
A plain-language summary of the strongest evidence we have. We say when the data cannot answer a question.
Bottom line
Public data cannot grade this train line live. Check official alerts and dated observations below.
Available evidence: the official timetable, official service alerts, train research, and dated rider observations. None is presented as a live train position.
Schedule change check
This compares the current retained official schedule with the prior retained version. Schedule changes are facts about what was planned; they do not prove that a trip ran.
Current published schedule began September 18, 2026
We check the first Monday after the new schedule began and the Monday one week earlier. Every figure comes from the retained official GTFS versions named below.
At least one selected date uses added or removed calendar-date service. Treat this as holiday or special-service context, not ordinary weekday growth.

We will compare settled arrivals for the 14 days before and after the change. We publish the comparison only after both sides have at least 7 service days and 200 arrivals.
The public feed has no live O-Train positions or predictions. The schedule comparison is visible, but a train reliability before-and-after score cannot be produced from missing realtime rail data.
Checksums let anyone verify which retained timetable produced the counts. A changed count does not identify a cause, cancellation, operator decision, or passenger impact.
No live grade is published. Official alerts, the timetable, research, and dated observations stay separate and auditable until OC Transpo publishes dependable realtime rail data.
The public feed does not provide live train positions, arrival predictions, dependable passenger counts, or proof that a scheduled train ran. A timetable entry is not a live observation.
O-Train evidence
Trains are not in the public data feed
OC Transpo publishes live positions for its buses, and this site measures them: millions of bus arrivals every month, which is where every bus figure on this site comes from. The same public feed carries no train positions, so this site has never recorded a single train arrival. Nothing here can tell you where a train is, or whether Lines 1, 2 and 4 run on time.
This is a gap in what is published, not a gap in the trains. If train positions were published the way bus positions already are, riders would get the same record for rail that they have for every bus route on this site.
These are rider sightings approved by a moderator. They show a reported time and place. They are not official train positions, a complete train count, or proof of a cause.
No approved rider observation matches this place or line in the last 31 days. That does not mean no train ran or no problem occurred.
Check the numbers
This route has more than one official schedule record. We keep each record separate so the totals stay checkable and we do not invent a combined worst-case result.

No reliability cohort can be safely matched to this public route. No representative schedule record is substituted.
The current public route group, its published schedule variants and stop patterns, current operations, and matching observed reliability where available.
1 current GTFS route record variants are grouped by operator and public route number. Stop patterns remain tied to their published variant; aggregated reliability records are not merged into an invented percentile.
