Amtrak No. 1402 was an SC-44 (Charger) type diesel locomotive built by Siemens Mobility (exact date and year unknown) for the National Railroad Passenger Corporation, also known as Amtrak. The Siemens Charger locomotives were initially purchased by Amtrak in order to replace their older GE Genesis series and EMD F59PHI type locomotives. It was assigned to Amtrak's Cascades services operating between the US states of Washington and Oregon.
On December 18, 2017, it was badly wrecked in the DuPont train derailment in DuPont, Washington. An investigation was launched into the cause of the derailment, and according to former Amtrak CEO Richard Anderson, he said that Positive Train Control (PTC) was not active on the line at the time. After the horrific accident, it was deemed damaged beyond repair and scrapped along with all of the passenger cars involved in the derailment. The helper locomotive, that being P42DC (Genesis) No. 181, was undamaged since it remained on the tracks after the derailment and quickly returned back to service with Amtrak where it still operates as of today. The accident was yet another red flag at some railroads' lack of progress in fully implementing PTC technology at the time, especially for Amtrak, who were already in hot water after the Philadelphia train derailment, also known as the Amtrak 188 incident, that occurred on May 12, 2015 on Amtrak's Northeast Corridor.
