Spotted these marks on the Metra tracks near 55/56/57, and wondered what they were for. My best guess is that they indicate some area for repair, but I’m really not certain.
The marks are made on two separate tracks – tracks that seem to be primarily for freighter/cargo lines. But what strikes me is that they seem to be symmetrical. So maybe something is getting installed or built here? the fact that they seem to be identical marks seems to argue against these being repairs.
Wonder if we’re going to see another rail crew?
