Related to Choo Choo Johnny's post: I just read on the industry news wire that RR's are closing there auto ramps (unloading distribution points) because of so many dealership's being closed but are suspecting a surge once they open up again.
Last year auto (carried in/on Auto Racks) and auto parts (most carried in containers) represented 6% of rail traffic.
Over all rail traffic this year is down 7.2% from last year's figures, if I remember right, last year's figures for the year were about the same or a tad lower do to weather conditions and the Tariff Wars.
