| Tower 55 interlocking in Fort Worth was originally commissioned in 1904, and this brick building was constructed in the 1930’s. Control of the interlocking was transferred from this tower to Union Pacific’s nearby Centennial Yard in 1995, then to UP’s Harriman Dispatching Center in Omaha, then to Spring, Texas and then back to Omaha. After the tower was no longer used to control trains, it was retained for use by maintenance personnel, but it was finally demolished in November 2022. |
