I used to live a few doors away from the R.I. commuter tracks between the Station at Brainerd and Gresham Junction on the south side of Chicago until September,1968. Parallel to the R.I. tracks were two C&O tracks mostly used by freights but once a day I recall an eastbound C&O passenger train , which I never knew where it was going , would pass and have a roadrailer on the rear end. After the train passed the tower at Gresham Junction it would cross over Vincennes Ave. and then immediately cross the R.I. north/south mainline. I never remember seeing the westbound counter part to that train, if it had one and always wondered where those freight were going to and from. I believe those C&O tracks were lifted and I read recently here on Railroad.net that the area around Gresham Junction is not a place to go either during the day or night.
