NTSB reports failed braking system caused the death of two members
In a press release issued Jan. 25, the National Transportation Safety Board (NTSB) determined that an airbrake failure caused a fatal collision between two Union Pacific trains in Granite Canyon, Wyo. on Oct. 4, 2018.
Local 446 members Benjamin Brozovich and Jason V. Martinez were killed in the collision. According to the NTSB, the collision occurred when the air brakes on their eastbound freight train failed while going down a hill. An air flow restriction in the brake pipe caused the air brake system to fail, and the end-of-train device failed to respond to an emergency brake command, the NTSB reported. As a result, the runaway train collided with the rear of a stopped UP train while going approximately 55 mph.
