It's more complicated though.
Portland OR already has I5 running right through town and very near the port. Presumably it also has a number of rail lines.
Coos Bay is, relatively speaking, in the middle of nowhere along the Oregon coast, in a very mountainous region.
Refurbishing the rail line is a great idea, but surely they'd also want some of these to be offloaded to trucks, which is going to require an expansion in the highway infrastructure, at least with the respect of carrying heavier loads more frequently if not adding a lane in each direction so that they can accommodate the traffic increase.
