To quote the Union Pacific website "Tower 55 is one of the nation’s busiest and most congested rail intersections. Located just south of downtown Fort Worth, Texas, Tower 55 holds vital national and international significance, connecting freight and passenger travel between the West Coast, Southeast, Midwest, Gulf Coast, Mexico, and Canada." The current three-story brick structure was built in 1941 while the original Tower 55 crossing was built in 1904. At the time it was the crossing of the Texas & Pacific with the Katy, the Santa Fe, and the Houston & Texas Central (H&TC, successor to the FW&NO owned by Southern Pacific). Today, the junction sees frequent UP and BNSF freight trains. Trinity Rail Express and Amtrak also traverse rails at this location. The I-30 and I-35 highway interchanges loom above. A Southbound UP grain train is seen taking the diamond on a Saturday afternoon.
