A small home that sits all by itself in Penn Hills along an long abandoned Trolley line . Why was it built there?

If you look way up on the hill side behind where Hippos bar once sat and is now a car lot at Verona and Coal Hollow road  you will see a yellow wood framed house it sits there all by itself. But at one time the Pittsburgh Railways trolley route which followed Verona road out of Wilkinsburg and went across the Coal hollow Valley via large steel bridge on its way to Oakmont  ran right in front of it. Now owned by a Dr. no one seems to know its history. But I suspect it was built by the people who built and maintained the right of way the trolley used. makes sense who would want a house right on a trolley line. in virtually middle of no where and nothing else around it.

Now it would  not be that unusual because several road houses and hotels where built right beside the railroad tracks when Pa. railroad was built thru this area and since there was a massive bridge and over 1 mile of right of way to be built into a steep hill you had to house workers some where
of course its all speculation but it makes the most logical explanation and anybody knowing the truth are long gone the line was put thru in early 1900's  and abandoned in late 50's but there are also rumors it was a speak easy in the 20s makes sense sitting up there all alone

Unfortunately the house is in very poor shape and falling in on itself  so if it did play any kind of significance with the trolley line many clues are probably lost now.
Remember this is private property so be advised you are trespassing if you would try to go up and explore it . and signs have been pasted and maintained over the years.
