Amtrak is having its issues, too, due to staff shortages. And car shortages due to staff shortages at the maintenance facilities. 7 or 8 cars just went out of service with yesterdays derailment (due to a dump truck being on the tracks which the train hit at 90 mph). Even if the cars can be repaired quickly, they won't be until the NTSB is done with their investigation and most, if not all, legal matters are taken care of. I'm assuming the cars that derailed in Montana last year are still "in storage" for the same reason.
I still think train travel is safe and I still enjoy taking the trains.
Google is your friend for finding info about traveling by train. I do suggest NOT using Amtrak Vacations. They are not affiliated with Amtrak other than being allowed to use Amtrak in its name. Its a travel agency and I've heard bad things about them.
