No it would not have, as another posted, the NTSB has reported this was a bearing failure[1]. Bearing failures account for 5.9% of all train derailments[2]. It's possible to help prevent this (not fully as many things derail trains) with more sensors[3] and tighter maintenance checks. This was most likely due to a lack of maintenance.

In another universe, ECP brakes would have saved the day. It sounds like the Trump administration still deserves criticism for decaying train safety.

  > ECP brakes would have saved the day Citation needed. It sounds like all administrations (especially those currently in charge) deserve criticism for not focusing on the correct regulations for train safety. Requiring something that isn't needed doesn't help... It can hurt as it takes resources away from actual necessities, like sensors, and tighter maintenance inspections.

    Did you just ask for a citation from a hypothetical universe?

      Well then, we’ll have to do with a hypothetical citation from a real universe. The U.S. National Transportation Safety Board (NTSB) found that a train derailment near Philadelphia, Pennsylvania in May 2015 was prevented from being a disaster thanks to the train’s Emergency Control Power (ECP) brakes. According to the NTSB report, the ECP brakes, which are activated when the engineer loses control of the train, stopped the train within 1.25 seconds of the engineer’s attempts to stop it, preventing it from derailing. The ECP brakes are the most efficient braking system available, allowing trains to stop within a very short amount of time. Without them, the tragic derailment of Amtrak Train No. 188 may have been much worse. "U.S. National Transportation Safety Board. "Investigation Report: Derailment of Amtrak Train No. 188 Near Philadelphia, Pennsylvania, on May 12, 2015."

      Yeah how absurd of me to me to ask for their reasoning. Not absurd at all to bring up another universe... I ignored that silly part of their statement as you should have.

  Read the link I posted above. It estimates braking distance with EPC vs pneumatic along with reductions in cars that derail. It DOES reduce breaking time in emergency stops which has fewer cars derail but I don't know if it is enough of a reduction to be worthwhile. I don't think it would have dramatically reduced the number of cars that derailed in this accident. I am willing to be proven wrong.
