Northeastern temperature(s) has/have been relatively mild. Our world would see coal as an on demand need. A/C so far this summer, late afternoon, Pittsburgh area. My guess coal trains waiting for that 100 degree day. Us, older, Pennsylvania talk about days before A/C. Economic pressures via post pandemic, some open the windows. IMO.
A siding that could handle 140 coal cars would be rare. ??? IMO. May account for splitting the train between two sidings. ???
