Non-IFOPT IDs [link]
Stops in DELFI's feed should use IFOPTs as stop ID. Some do, some do not, and some use an IFOPT suffixed by one or multiple _G. The table shows correponding counts.
See also GTFS issue 115.

Not in Germany/Europe [link]
The list shows all stations, platforms, misc objects that violate at least one of the following criteria:
- Longitude is between 5.67 and 15.14 and ID starts with "de:".
- Latitude is between 47.19 and 55.13 and ID starts with "de:".
- Longitude is between -10.3 and 32.2 and ID.
- Latitude is between 36.2 and 70 and ID.

No objects outside Germany/Europe found.
Multiple objects at same location [link]
The three lists below show all stations, platforms, misc objects sharing their location with another object of same type. Two objects are considered "at the same location" if their distance is at most 1 meters. All objects of same type and location have a common group ID.
See also GTFS issue 44.
Stations [link]
No locations with multiple stations found.
Platforms [link]
Found 11 platforms sharing their location with another platform.

Duplicate trips [link]
A GTFS feed may (but shouldn't) contain duplicate trips. Two trips are considered identical if all of the following criteria are satisfied:
- Departure times at first stop are identical.
- Arrival times at last stop are identical.
- Both trips have the same number of stops.
- Stops of both trips are pairwise (in direction of travel) identical (same ID) or at least closely spaced (distance at most 150 meters).
- Both trips share at least one service day.
See also GTFS issue 89.
Pairs of duplicate trips [link]
Column "identical stops" contains "True" if all stop pairs of the two trips are identical (same ID). If at least one stop pair has different IDs, the value is "False". Last two columns show how many of each trip's service days overlap with the other trip. A value of 100 in both columns thus means that all service days of both trips are identical.
Found 19 pairs of duplicate trips.
Trip pairs with 100 per cent service day overlap: 10
Trip pairs with partial service day overlap: 9
