The train was not equipped with ECP brakes; instead its locomotive used dynamic braking — electric traction motors acting as generators, which slow the train and dissipate mechanical energy as heat.

These include the air suspension; the panoramic sunroof; the acoustic window glass; and a suite of driver-assistance technology, including all-speed adaptive cruise control with dynamic braking and lane-departure warning; rearview camera and parking sensors fore and aft.

Crash-imminent braking automatically stops a car if sensors detect a possible crash, while dynamic braking adds force to the brakes if the driver isn’t pressing hard enough to avoid a crash.
