And the south side. Here's the scale itself. Note the two rails on each side, one on the scale beam and the other not. It is not dual gauge track. In the background a Pennsylvania RR GM switcher moves cars around.
Today there are only two tracks here.
In the right background a Pennsy train is passing on the main. Jacks tower represented the end of the old main through Mount Union where it connected to the new 1907 main. There were and still are crossover tracks here as well. The tower is still in service at this shot. It has long since been demolished.
