4 years ago Note that the actual CSV file contents for any GTFS file aren't guaranteed to be in order by any field.
From a quick look at the Python code linked above, it looks like these rules are all based on first sorting the shapes.txt file by shape_pt_sequence, and then iterating through the records examining the other fields from shapes.txt.

Is your feature request related to a problem? Please describe. Every points in a shape should be in order. This is a GTFS rule implemented in Google Python validator as AddShapePointObjectUnsorted.
Describe the solution you'd like Actual Google GTFS validator behaviour : verifies if shape point sequence is valid while adding it. Verifies if points are in good order by verifying distance from the beginning of the shape. https://github.com/google/transitfeed/blob/d727e97cb66ac2ca2d699a382ea1d449ee26c2a1/transitfeed/shape.py#L54
