My guess is for a mix of reasons:
-Backlog of maintenance
-Refreshing Superliners
-OBS Shortage
And why is not possible for Amtrak to exhibit a modicum of transparency. If these things challenges are true, then say so and attempt to assure the traveling public and the non-profit organization that represents the most loyal passengers, that fixes are in the works and here's what we can expect. Wait, ok, sorry. I forgot about Amtrak's record of delivering on promises.
