Based on the comments, there are a LOT of places on a LOT of routes with bad tracks. A few seem to be on Amtrak owned tracks but most, by far, are on freight tracks and we know how much they care about passenger service!
Once again, vote for me_little_me as emperor and dictator and I promise to arrest all the offending freight chiefs of maintenance and tie them to the underside of a train where their heads will bounce up and down against the steel underbodies of the cars. I won't even mention what will happen to the executives and board members. It's too horrible to contemplate. I do assure you that there will be a lot of changes at the top of these companies because of the number of vacancies.
