Twin Cities 400

The 400 (later named the Twin Cities 400) was a named passenger train operated by the Chicago and North Western Railway between Chicago and Saint Paul, with a final stop in Minneapolis. The train took its name from the schedule of 400 miles between the cities in 400 minutes, and was also a nod to "The Four Hundred Club", a term coined by Ward McAllister to refer to the social elite of New York City in the late 19th century. It was an express train with limited stops between Chicago and the Twin Cities. The "400" ran from 1935 to 1963 on the Chicago to Twin Cities route. The C&NW later named their other passenger trains using the number "400".
