Amtrak’s Missouri River Runner, which has service between Kansas City and St. Louis, will have a temporary schedule change to accommodate repairs to the Union Pacific railroad lines it uses. October 16 – 20 trains will leave Union Station in Kansas City at 6:00 A.M. instead of its regularly scheduled 8:15 A.M. Trains will arrive in St. Louis at 11:40 A.M. instead of 1:55 P.M.
