Designating a stop as a Depot indicates that this stop is used for parking a vehicle.  This could be a school location or a driver’s home for example.  To create a depot, there will need to be a stop created at the location.  

To indicate that a stop is also a vehicle depot, create or locate the stop in the Stops tab.

In the General sub-tab of the stop, click the indicator that this stop is a Bus Depot.

Locations that are set to be a Depot will have a “Depot” badge in the stop list.
