Distant Signal

Mystery of the Red Signal (2025x4)

Air date: Mar 20, 2025

Why do railroads use those mysterious combinations of signal lights? For years, I've wondered why some places have a red light that never changes. I do an UN-official investigation into the reason. Plus some easy railfanning spots near Tampa for Spring Break and beach visitors. Then we'll stop and enjoy a homemade strawberry milkshake!
