stop_time_timepoint_without_times: exact timepoint with no time Error

A stop time in stop_times.txt is flagged as an exact timepoint but has neither an arrival nor a departure time. Why it happens and how to fix it.

Updated on 21 October 2026

What this rule means

The timepoint field of stop_times.txt says whether a stop time's times are exact (1) or approximate (0). A stop time flagged as exact must carry its times: arrival_time and departure_time. The rule fires on a stop time with timepoint=1 and no time. The GTFS Express catalogue also treats an empty timepoint as exact.

Severity: error.

Why it matters

A timepoint without a time contradicts itself: the feed promises a scheduled time at that stop and does not give it. Tools that interpolate times at intermediate stops rely on the timed points; an empty one removes an anchor, and some consumers drop the trip.

Common causes

An export that sets timepoint to 1 on every stop time by default, although only some stops have a time.
Times deleted at intermediate stops to let interpolation work, without setting timepoint to 0.
A stop inserted into a trip without a time, with the timepoint value copied from a neighbouring row.

How to fix it

There are two possible fixes, depending on what is true on the street. If the stop is a timing point, fill in arrival_time and departure_time from the timetable. If it is not, set timepoint to 0 and leave the times empty: consumers interpolate them between the timed points. The first and last stops of a trip must always have their times (see missing_trip_edge).

In GTFS Express, each occurrence in the report names the stop time and the field. "Fix one by one" opens the stop time in the editor; each correction is a retouche in the draft, and "Re-validate" runs the validator again.

Example

trip_id,arrival_time,departure_time,stop_id,stop_sequence,timepoint
T501,07:00:00,07:00:00,S100,1,1
T501,,,S110,2,1
T501,07:12:00,07:12:00,S120,3,1

Fixed, stop S110 not being a timing point:

trip_id,arrival_time,departure_time,stop_id,stop_sequence,timepoint
T501,07:00:00,07:00:00,S100,1,1
T501,,,S110,2,0
T501,07:12:00,07:12:00,S120,3,1
