Posted by Sand Box John on Tue Jul 3 10:24:39 2007, in response to Re: Elevated freight railroads, posted by aem7ac on Mon Jul 2 16:05:22 2007. Some of Southern's alignment out of Washington D.C. Union Station is elevated in the vicinity of the Potomac Riverfront. This is a classic 'el' as in a steel structure.That steel structure is a bridge that is between retained fills on either side of Maine Avenue SW that are part of the north approach to the bridge that crosses the Potomac River. The alignment from east of South Capitol Street to west of 7th Street SW is on a retained fill. There use to be a connection on the north side of the retained fill west of 6th Street that served cold storage warehouse between 4th and 6th Streets SW. A bridge similar the bridges that cross Maine Avenue crossed 6th Street entering the second floor of the building. The present configuration of the railroad alignment through Washington DC was built near the beginning of the last century as part of the Union Station construction project.
