To request a public transport route using the CalculateRouteRequest service, you must specify the start (waypoint0) and destination (waypoint1) waypoints and choose a public transport routing mode. Additionally, you must include your authentication credentials, app_id and app_code with each request to the Routing API.

This is an example estimated public transport routing request for alternative routes, in addition to the main route.
