Fresh vehicle positions appear on the route below. A marker stops moving when the evidence runs out. We do not invent movement.
The line is the official route. Dots show published stops, buses seen now and stops named in current notices.

Markers move between GPS fixes using measured progress along the published route. They pause after one measured reporting interval, on a measured standstill, or when evidence becomes stale.
Repeated problem stops: MERIVALE / JAMIE, MERIVALE / SLACK, MERIVALE / CLEOPATRA, 1755 MERIVALE, MERIVALE / CLYDE and 7 more. These are highlighted from route-specific settled arrivals with at least 60 observations over 3 days; the pattern does not prove a cause.

Verdict
Timetable short by 3.2 to 3.5 min in 5 hours of the day.
Buses already leave about 2.4 min late and hold it to the end. The running time is right; the terminal is the problem.
Runs about 1.5 min early, 01:00.
Gaps All measured hours: waits run 2.3 min longer than the timetable promises.
Next investigation: test terminal recovery and the preceding trip. The arrival pattern alone does not establish the cause.

|---|---|---|---|
| ProblemLate by the timetable | 07:00 to 09:00 · 15:00 to 18:00 | 3.2 min late · 3.5 min late | Recovery time at the terminal |
| ProblemLong gaps on a frequent route | All measured hours | 2.3 min extra wait | Manage the headway |
| ProblemRunning early | 01:00 | 1.5 min early | Less running time, or holding points |
Route check
A plain-language summary of the strongest evidence we have. We say when the data cannot answer a question.
Bottom line
Service is unreliable often enough to affect riders.
74 in 100 arrivals were within 5 minutes of schedule · 113,046 arrivals checkedConfidence in this summary: High
Based on 113,046 arrivals over 20 weekdays, from Aug 20, 2026 to Sep 19, 2026.
Updated Sep 19, 2026, 1:32 p.m.
These are repeated patterns, not one bad day or an unverified rider report. They are measured the same way as the verdict above, over the same arrivals, but they are counted per stop rather than per hour, so the two lists need not match line for line.
No current official notice matches this route.

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.
Still collecting: before has 77,113 arrivals over 14 days; after has 8,228 arrivals over 1 days. No improvement or decline is claimed yet.
Checksums let anyone verify which retained timetable produced the counts. A changed count does not identify a cause, cancellation, operator decision, or passenger impact.
We compare observed arrivals with the official schedule. A result needs at least 200 arrivals. Within 5 minutes is the rider-facing target used here.
The public feed does not provide dependable passenger counts or passed-up-rider events. A missing position does not by itself prove a cancellation, no-show, short turn or cause.
Provisional results, published evidence
Every hour below is backed by this route’s settled arrivals. “On time” means no more than five minutes early or late, so a bus that leaves very early counts as a failure for the waiting rider.

6 hourly block(s) are below 70% across at least three service days: a repeated pattern, not one bad day.
639 / 772 scheduled trips published at least one position across 6 service days (82.8%).
This is not a confirmed no-show. A missing position can mean a cancelled or missed bus, but it can also mean an unassigned trip ID or an operator-feed gap. Otranspo publishes the gap because it matters to riders while keeping the conclusion honest.
Arrival check: the last prediction within ten minutes of arrival, counted once per trip, stop and service date. Trip check: the timetable kept before each service day, matched to recorded positions. Exact IDs are preferred; an OC timetable suffix is matched only to one trip on the same route and date with an overlapping time window. Missing timetables, ambiguous matches and feed gaps stay labelled; they are not confirmed no-shows. Sources and limitations.

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.
