  • Can't believe they still run a tower like that. Was this some rail tour?

  • The tower is no longer operational.

  • there are numerous active towers on the New York and Chicago subway/elevated systems, although none have this type of "armstrong" interlocking machine as far as I know...

  • There are some interlocking towers yet operational, like Dolton Tower in Illinois. 19th Century technology that still functions! Fantastic job preserving the tower!!

  • Oh. It would've been remarkable if it was though.

  • CHIEF!
