This documentary investigates why the Amtrak SDP40F was removed from passenger service after a series of high-profile derailments in the 1970s. Built quickly during Amtrak’s chaotic early years, the SDP40F combined a heavy freight locomotive platform with passenger-specific equipment that subtly altered its dynamics at speed. Federal investigations revealed a hidden physics problem rather than mechanical failure or crew error. The result reshaped how passenger locomotives are designed—and why some freight solutions cannot be adapted safely.
