signals under electrification

[NW Mailing List]

Having grown up in Bluefield, PL's all I can remember. I don't have any documentation, but I doubt semaphores lasting until the end of electrification in 1950.

 I seem to recall that the first installation of PL signals on the N&W was around 1920.  The brunt of the Pokey electrification was completed by this time, so it was signaled with semaphores on the catenary supports.  I don't recall seeing any photos showing PL signalling in the electrified section.Conjecture:  The N&W needed/chose to retain semaphore signalling in electrified territory until electrification was discontinued in 1950.  I would assume that as the catenary was removed, PL signals were installed in this area.  So Bluefield to Iaeger would have seen PL signals for only about ten years - from the end of electrification until the change to CPLs around 1960.  Would this make the electrified part of the Pokey the last portion of the N&W to be upgraded from semaphores to PLs?  Can anyone confirm, deny or add to any of my speculations?Jim Cochran
