Not to go too far off-topic...
The third photo appears to be the diamond of a track that curved past the lighthouse and went directly up to the bridge. Wasn't there another diamond that went from the north yard, across the RWO, and into the old foundry? If so, it must have gone up-grade, across the RWO, and down-grade to the foundry?
I am also curious about the freight car trucks. Are those considered friction bearing or roller bearing?
I'm surprised BR&P hasn't replied - he must be taking a nap.
Yes, it is a PC train. Yes, there was another diamond, one that allowed today's Charlotte branch to cross the Hojack at an almost 90 degree angle. The historical aerials website (my only source at the moment) shows the trackage there in a 1933 map, but gone in a 1951 aerial photo. And finally, yes, those are friction bearing trucks. Roller bearings gradually replaced friction bearings for two major reasons: 1) roller bearings provide less rolling resistance, so motive power can be reduced for any given application (the proverbial "do more with less"); and 2) roller bearings require significantly less maintenance than friction bearings.
