There\'s another runaround track on Goose Island north of Division Street and on the east side of Cherry Street if the track is blocked outside of Big Bay Lumber as shown in the photo. They could then use this runaround track to the north for swapping out empties for loads though it would involve crossing busy Division Street twice.
They could also leave a new load for Big Bay on Kingsburynorth of North Avenue but just south of the Goose Island lead, retrieve the empty, then couple the empty onto the loaded car and shove them both back down, uncoupling the load from the empty in front of Big Bay, then returning with just the empty.
I have seen crews use both methods over the years.
Yes, Blommer still sees rail service on its lower level where they built a crypt under the tracks for direct delivery into the plant.
