Here's my view from Kearsley Tower as a southbound passes on a summer Sunday in 1970. At this time, it was single track all the way from the Flint River (S. McGrew) to the next actual siding at Newark. That track to the right of the train was just a yard track that came off the south end of the Kearsley pass. In a couple years it would be completely upgraded to become #2 main track. Here's a link to the photo in case it doesn't show up for you:
