Ryan’s point was about how you can’t “magic wand” away the need to modify equipment to work for this purpose. It takes actual resources (financial and human) to do that. And my (and others’) point is, and has been, that there is virtually no scenario in which the resources needed to do that wouldn’t be better directed towards getting Amtrak’s existing fleet back in good condition.
Even assuming that Amtrak today has plenty of money to spend, “just contract it out” is again magic-wanding away the troubles of manpower. Staffing shortages aren’t just an Amtrak thing. They are a nationwide problem, affecting nearly every shop and every industry. Who are you going to get to do the work that has a ton of shop capacity just sitting around waiting to modify a bunch of railcars?
If shops really did have spare capacity sitting around (again, doubtful), why not subcontract out the repair of existing equipment to get it back in running condition?
