The last coal movement for a coal yard of which I am aware on the C&E North Line was in 1973 when the Milwaukee Road picked up a load of empties from the CTA on the last run north of School Street at Buena Yard. A customer at the very end of the C&E South Line just past Grand received an occasional carload of coal for their own use.
The remains of a coal trestle can be seen at the former Roth Coal site north of Cortland Avenue and east of the river.
There were coal yards on the C&E South Line off Kingsbury and also on Goose Island at one time, among other locations.
A 1979 internal report by the Milwaukee Road did not list any coal yards on the C&E line so presumably they were gone by then.
