Thanks for the good info.

Someone told me either the GN or BN used power up the steep spur to the Boeing Everett 747 plant that was ballasted with concrete to get better traction. I raised an eyebrow when he said it 🤨 . Made me wonder if GN 598 or 599 worked that Boeing spur but others have said they were on the OC&E, so perhaps not.
