Brake failure probably caused a freight train collision that killed two crew members in southeastern Wyoming in 2018, according to U.S. accident investigators.
This crash in Wyoming involving two Union Pacific trains killed two.
NTSB
The National Transportation Safety Board determined on Jan. 25 that an airbrake failure caused the fatal, Oct. 4, 2018, collision between two Union Pacific trains in Granite Canyon, Wyo.
The collision occurred when the air brakes on an eastbound UP freight train failed while descending a hill. The NTSB determined 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 striking train collided with the rear of a standing UP freight train at about 55 mph, causing the lead locomotives of the striking train and railcars of both trains to derail. The locomotive engineer and conductor of the striking train were killed.

Researchers have raised the alarm over the drastic drop in the population of gray whales off the West Coast of the United States. According to the researchers, the sudden drop in gray whales population by almost one-quarter since 2016 closely mimics similar die-offs close to 2 decades ago.
NOAA Fisheries reported in a paper released last Tuesday that surveys counted at least 6,000 fewer migrating gray whales last winter, i.e. 21,000 compared with up to 27,000 in 2016.

Scientists Still in the Dark About Cause of Die-offs, Attribute Causes to the Environment
According to the agency, there is a strange mortality event which occurred in 2019. Dozens of gray whales were washed up on the beaches of the Pacific Ocean. Scientists have not been able to put the finger on what is causing this substantial die-off.
In a paper released Tuesday, NOAA Fisheries reported that surveys counted about 6,000 fewer migrating whales last winter, 21,000 as compared with 27,000 in 2016.
