Created in 1969 by the Oregon legislature, the district replaced five private bus companies that operated in the three counties: Multnomah, Washington, and Clackamas. TriMet started operating a light rail system, MAX, in 1986, which has since been expanded to 5 lines that now cover 59.7 miles (96.1 km), as well as the WES Commuter Rail line in 2009. It also provides the operators and maintenance personnel for the City of Portland-owned Portland Streetcar system. In addition to rail lines, TriMet provides the region's bus system, as well as LIFT paratransit service. There are 688 buses in TriMet's fleet that operate on 85 lines.
