Signal on the left: 4 pairs of Safetran 12x20 inch lights, a dead General Signals (Type 1?) electronic bell, a Safetran gate mechanism, and RECO gate lights.
Signal on the right: 4 pairs of Safetran 12x20 inch lights, a General Signals Type 2 electronic bell, a Safetran gate mechanism, and RECO gate lights.

This crossing is a bit of an interesting one. Both signals here were installed in the mid 1990s by NS, though in the early 2000s, the signal on the left had the original Safetran mechanical bell replaced with a General Signals e-bell, and with how faded it is, I'm betting that it was a Type 1. The right-hand signal retained its original mechanical bell until sometime between 2008 and 2013 when it was replaced with the current GS Type 2 e-bell. Sometime more recently (sometime after 2016), all but two pairs of the lights on the crossing were replaced with newer Safetran 12x20 inch lights for some reason, though the rear mast lights on the right-hand signal and one of the pairs of overhead lights on the left-hand signal were left in service. The GS e-bell on the far signal also likely died sometime recently, which is a bit of a shame. Hopefully it gets replaced with a GS Type 3 though.
