Loop Routes begin and end at the same Stop and have a few other unique attributes and requirements.
Loop Route-specific GTFS Requirements
Loop Routes must start and end at the same Stop. Partial Patterns (such as the last run of the day ending before completing the loop or returning to the garage,) are exempt from following this convention.
If a Stop is serviced multiple times, it cannot be re-selected from the Stop Order edit mode on the Map View. It must be added via List View. GTFS Manager will display the last stop sequence number in Map View.
If a rider is allowed to stay on the vehicle between Trips (such as boarding near the end of one loop, and riding through to a stop on the next loop,) the in-seat transfers allowed checkbox must be checked.
