As a young lad in on Jan 2, 1951 General Yardmaster Harmon Young hired me as a switchman to work on the steam engine number seven. I worked there until I went into the army in 1957. After the army I worked for the SLSF RR. Under the Houston Street bridge was my many many trips as we change to and fro between the eleven tracks at Dallas Union Station on the steam engine. On the West side of the bridge we had a Y that we turned trains and rr cars. The Y would hold seven rr cars. Once the Towerman put a TP frieght train under the bridge on the Y track and a load with auto frames that was too high destroyed some the bridge support beams. Th bridge as always a spot for drunks and folks that bumed rides on the freight trains. I have a lot of stories of Union Station in the early 1950s. I do not have any pictures.
i remember the old trolley and the sparks above it from the cables that ran it. amazed @ five years old!!
