The NTSB has finally released the results of their investigation into the possible mobile telephone usage by the engineer of the ill-fated Amtrak train in the Frankford Junction derailment. It certainly took them long enough.
Long story short: The mobile telephone had not been used by the engineer. So now the NTSB is back to square one in trying to determine why the train was going 106 miles per hour in a 50 mile per hour zone.
Here is an excerpt from the report:
"Analysis of the phone records does not indicate that any calls, texts, or data usage occurred during the time the engineer was operating the train. Amtrak’s records confirm that the engineer did not access the train’s Wi-Fi system while he was operating the locomotive."
