Scioto Signalling

[NW Mailing List]

Well for starters those are not “pl” or position light signals. Those are color light signals. Most of the colorized position light signals at intermediate locations such as this have been gone since the 1990’s. NS seemed to favor eliminating intermediate cpls first...

It’s interesting these Southern style signals have remained...
