In April 1996, I traveld to Ft. Worth to attend the BNSF stock holders meeting. After the meeting I walked over to Tower 55 to get some photos. It was my first, and only time, to see this interlocking. These are some of the photos I took that day; we won’t even mention the obvious thing about these photos.
Not sure if Tower 55 is the most photographed interlocking tower in the country, or if that honor goes to one of the interlocking towers in Chicago. In November 2022, Tower 55 was torn down. Here is a link to a video on YouTube.
