For the first 115 years of the transit system in the Milwaukee area, the system was self-sustaining and ran only on the fares collected from riders. In fact, Milwaukee was one of the last cities in the country to have a privately owned, profit- making transit company. But on July 1, 1975, Milwaukee County acquired ownership of the transit system in order to sustain its existence. It contracted Milwaukee Transport Services, Inc. (MTS) to handle the newly named Milwaukee County Transit System (MCTS) bus operation.
Milwaukee County invested in the transit system and led them through significant ridership growth during the 1980s and early 1990s. New services were added such as the Metrolink express service in 1992. Those traveling to special events in the summer, such as Summerfest and the Wisconsin State Fair, relied heavily on the easy-to-use express service. There was even a short time where “trolleys” returned in the early 2000s. Ten Chance Coach Trolley replica buses connected visitors and residents to work, shopping and entertainment venues in Downtown Milwaukee.
Today, the transit system is operated out of four locations. The system’s administration and fleet maintenance operations were previously located at Cold Spring Shops on Highland Boulevard which in the early 1900s was the site of many innovations including streetcar construction, building of bus bodies and the invention of the transit windshield wiper. But the administration and fleet maintenance operations moved to the present facilities on North 17th Street in October 1985. Every day, operators pull buses out of two stations: Fond du Lac and Kinnickinnic. Each facility also houses a garage to fuel, clean and provide day-to-day maintenance to ensure vehicles run properly. A third station and garage, Fiebrantz, closed in 2018.
