I doubt it was originally equipped as such, as Ron mentioned, the entire signaled portion of the Buchanan branch was all PL/CPL's when signaled. Signals were replaced as needed with tri-light signals starting in the late 80's. An odd example would be the intermediate signal on the Pokey main at Flat top. It is a cantilever signal where the EB aspect is a CPL and the WB aspect is a tri-light which looks like something off the Southern. The one you are referring to was likely replaced due to a derailment or something, happened all the time. But NS really started replacing them in earnest in the late 90's through today.
