Evanston's growth occurred largely because of its accessibility from Chicago by rail. The Northwestern founders did not finalize their commitment to siting the university there until they were assured the Chicago & Milwaukee railroad line would run there. C&M trains began stopping in Evanston in 1855. Evanston later experienced rapid growth as one of the first streetcar suburbs. The North Shore Line which gave the area its nickname started at Church Street in Evanston and continued up to Waukegan.
Transit continues to make Evanston attractive today. The CTA's Purple Line, part of the Chicago 'L' system, runs through Evanston. From its terminal at Howard in Chicago, the line heads north to the South Blvd, Main, Dempster, Davis, Foster, Noyes, and Central stations, before terminating at Linden in Wilmette. Metra's Union Pacific/North Line also serves Evanston, with stations at Main Street, Davis Street and Central Street, the first two being adjacent to Purple Line stations. The CTA's Yellow Line also runs through the city, though it only stops at Howard. Evanston also contains several I-GO cars.
Evanston is also served by six CTA bus routes as well as four Pace bus routes.
