The Terminal Railroad Association of St. Louis (TRRA) owned the St. Louis Union Station and the two bridges that could carry railroad traffic across the Mississippi River. Like Chicago, many of the eastern and western railroads terminated at this city. Unlike Chicago, the only terminal railroad connecting the trunk railroads was TRRA. (Chicago had the Indiana Harbor Belt, B&OCT, EJ&E and other terminal railroads. It also had six train stations instead of just the one Union Station in St. Louis.) The TRRA History emphases the ownership of the bridges whereas American-Rails emphases the ownership of the Union Station.
Madison Yard is their main yard.

TRRA... By Rail!
It is a rare treat to be able to traverse and observe the trackage of the Terminal Railroad Association of St. Louis (TRRA) on a special passenger train. However, this opportunity presented itself this past Sunday, when a trip was sponsored by several of St Louis' serving railroads on behalf of the American Association of Railroad Superintendents for its annual meeting, held in the Gateway to the West. Although Amtrak trains to and from Chicago or Kansas City do utilize TRRA routes to access the new St. Louis Amtrak Station, much of the Terminal Railroad is rarely visited by passenger trains. I took many photographs, but here are some representative views of the always fascinating bridgework around St. Louis, as well as its iconic Arch.

Dave Hopson I've seen movies of trains on the lower level of the second bridge in front of you.Mark Hinsdale Yes, PRR used the lower level of the Eads Bridge to get across the Mississippi. Today those two tracks carry Metrorail (light rail) trains between Belleville & St. Louis.
