Joint Line

FORMERLY Chicago & Alton Railroad/Gulf Mobile & Ohio Railroad
OPENED 1865 by Alton & St. Louis Railroad
ABS installed 1940
PASSENGER SERVICE: Amtrak St. Louis Route

A paired track has always existed, as this route shares a route with other railroads approaching the St. Louis area. In much of the St. Louis area, all railroads operated via the jointly owned Terminal Railroad Association of St. Louis (TRRA). And Amtrak trains to and from Chicago are able to enter and exit St. Louis via two different routes. Historically, trains would usually switch to and from the TRRA at WR Tower, crossing the Mississippi River via Merchants Bridge, the most northerly of the river crossings in St. Louis. But in recent years, trains would more often use the MacArthur Bridge, immediately west of downtown St. Louis. The connection with the TRRA for that route is at Q Tower.
