According to a preliminary report by the National Transportation Safety Board (NTSB), a wheel bearing failure likely caused the East Palestine train derailment.
The NTSB report stated:
Train 32N passed three HBD systems on its trip before the derailment. At MP 79.9, the suspect bearing from the 23rd car had a recorded temperature of 38°F above ambient temperature. When train 32N passed the next HBD, at MP 69.01, the bearing’s recorded temperature was 103°F above ambient. The third HBD, at MP 49.81, recorded the suspect bearing’s temperature at 253°F above ambient.
Remember 23rd car.
