The Westmoreland County Transit Authority was created in 1978 by the county as a public and private partnership.
The authority owns its buses, but the service is operated by a private company, which hires drivers.
The authority's fleet has 43 buses -- ranging from small 22-passenger van buses to 40-foot deluxe road coaches.
The fleet has 25 large buses that seat 49 passengers; 16 buses that are 30 feet long with 28 seats, and two hybrid 22-passenger buses that are about 20 feet long.
The authority had 564,000 one-way riders in the year ending July 1. Westmoreland residents commuting to Pittsburgh made 274,000 of those trips. About 77,000 seniors used the service, as well.
Average daily ridership was about 2,500.
