Every weekday hundreds of thousands of passengers wend their way into and around the Windy City via the Northeast Illinois Regional Commuter Railroad, better known as Metra. The company provides rail service in greater Chicago via 11 lines that branch out from the central business district. Portions of the Metra system's 500-plus miles of track are owned by the company; the rest is leased from freight railroads such as Union Pacific and Burlington Northern Santa Fe , which also contract to operate some Metra trains. The system includes about 230 stations. Metra's board of directors is appointed by the City of Chicago and surrounding counties. The company is part of Illinois' Regional Transportation Authority.
