You mean Amtrak South Bay Trailer, right? LOL.Uh, well, yeah. South Bay is definitely in the running for the "lowest active railroad tower in the world" award.
For a short time before the current BET was built, Tower H was also located in a portable office trailer. Unlike South Bay, the trailer was placed atop a raised platform about 15 feet tall, so it was still a "tower" in a sense. The presently unused Tower 1 at South Station is built that way as well.
