A couple of years ago when I started to build this layout (I still am), there was an area that was supposed to be Pennsylvania Station.
Unfortunately, ending up in a position where I could never afford to buy the TrainWorx model of this building, caused me to abandon that plan.
Thus, most of the tracks, spurs, and sidings were removed from the "dark" bottom level, with only the reverse loop remaining.
It was much to my surprise 3 years later, when I was looking for my Pennsy passenger cars and could not find them.
I finally decided to peer into the dark tunnel portal leading to what was once supposed to be Penn Station.
What I found was the expected reverse loop, but what I did not expect to find was 2 sidings!
As I peered into the darkness, my eyes adjusted, and there to my relief were the long lost missing Pennsy passenger cars sitting in the deeper darkness on the outside siding.
Here is a photo I took of this discovery, see below!
