The NS Altavista district is a low grad coal route between Roanoke and Abiline, VA and I just saw some current photos showing that it has somehow avoided the mass re-signaling efforts that hit the N&W main line via Lynchburg. I'm not sure how similar it is to the Shenandoah District, which had its classic signaling refreshed (but not replaced) around the year 2000, but from what I can see most of the interlockings are still equipped with N&W style color PL's.
Still, nothing lasts forever and ALTAVISTA interlocking in Altavista, VA has the Darth Vaders up and ready to take over. Other interlockings seem to be OK, but if you live anywhere nearby, put this whole route on your must see list. The Altavista district is somewhat isolated and low traffic so it doesn't attract a lot of photography. It definitely needs some attention from the railfan community seeing the general lack of good signaling options.
