Yes, everything is blocked at North Ave. Yard. Half of the tracks have been torn out of Grand Ave. Yard and I usually find it empty. Think there might be 4 tracks left. Sometimes find them switching around 10 a.m. or so. Several times I've seen them leave the empties and return in the afternoon to retrieve them. Other times the cars have remained overnight. Never seems to be a set pattern.
As for Blommer, I've seen two moves done within one day. Also have seen hoppers sitting alone in Grand Ave. Yard. Just the other day they pulled all the tank cars that have been sitting on the old Sun Times lead.
