What is interlining?
Interlining is a common practice in the transit industry that combines two or more independent routes that arrive and depart from a common terminal. For example, a bus can arrive at a stop on a university campus on one route and after a brief layover, leave on a different route. When the bus leaves on its new route, the head sign and automated announcements get updates seamlessly. Interlining eliminates extended periods of down time where a bus would just be parked and out of service.
