Well youre never too old to learn something. Ive known of this building for 50+ years, a similar one east of town belongs to the water department so I always assumed this did too.
Imagine my surprise when I learned it was a power station for the Texas Interurban Railway, a commuter rail enterprise that was way ahead of its time. I think at some point maybe with a transfer or two one could leave Terrell and end up in downtown Dallas, Denton or Ft Worth.
The original mass transit company for North Texas as it were.
