so buttplug has identified exactly who's to blame for the derailment:
donald trump
~Secretary Pete Buttigieg
@SecretaryPete
We’re constrained by law on some areas of rail regulation (like the braking rule withdrawn by the Trump administration in 2018 because of a law passed by Congress in 2015), but we are using the powers we do have to keep people safe.~

here's the report he's referencing:
https://www.enotrans.org/article/dot-withdraws-ecp-brake-rule/
~The original rule was published in May 2015, but later that year, in response to complaints from railroads, Congress enacted section 7311 of the FAST Act which ordered GAO and Transportation Research Board reviews of the rule, and once those reviews were finished, ordered the Secretary of Transportation to take an “evidence-based approach” to a reevaluation of the rule.
In October 2016, GAO found fault with DOT’s original calculation of the benefits of the rule, and TRB reported two months ago that it was “unable to make a conclusive statement concerning the emergency performance of ECP brakes relative to other braking systems.”~
but it's still all trump's fault
