Interlocking towers played an important role in the safe operation of our country's railroads. They acted as traffic coordination centers at busy railroad junctions, allowing the safe passage of trains. Perhaps the busiest tower in the western U.S., with an average of over 100 movements in a 24 hour period, was Tower 55 located in Ft. Worth, Texas. Also known as the "Mixmaster" by locals, the tower utilized state of the art railroading technology up until its closing on May 15, 1995. Pentrex camera crews captured the nonstop action of Union Pacific, Santa Fe, Burlington Northern, Southern Pacific, and Amtrak trains at this famous Texas landmark prior to its abandonment. You'll also see fascinating interior shots of the control panels and computer screens that were in use during operation. As a bonus, exciting video sequences from the 1980s are also presented, as well as some striking night scenes of trains passing the Mixmaster. The current structure, which had seen over 50 years of service, now sits empty and idle due to a freeway construction project. The endless parade of passing trains is now controlled remotely from a nearby tower. Another railroad era has come to an end, but you can still experience the inner workings of an interlocking tower as passing trains pay their respects to Tower 55! 48 Minutes In Color with Stereo Sound and Narration Full-screen (4x3) Format TOWER 55 DVD T55DVDRegular price: $29.95Sale price: $14.98 Anchor Videos 3 Cedar Drive Montague, NJ 07827 Info: (973) 293-7788 Order: (800) 511-4140
