I grew up a few blocks North of the Elm Street station. I was told by an old-timer back in the 90's that the real reason the bridge/station was built was because a young boy named Able Eschelmann was killed at the pre-existing grade crossing on his way to school. It was a foggy morning. The locals were not happy and the new station was the result.
I spent a lot of time in the early 90's measuring the bridge structure and foundation of the station and collecting photos in order to build a module of the immediate area. The photos I have taken are some of the last before the the demolition. The Nickle Plate crossed just East of the platforms with an interchange track. I have begun an HO model of the station. It is complete on three sides and the colors are accurate as I found brick fragments in the remains of the foundation. I put off the front until I came up with a photo of the entry. The progress has stopped there.
Let me know if I can be of assistance.
