A train separation has occurred causing an emergency brake application. What step must be performed first when a separation occurs?
Determine what tools will be needed to make repairs and recharge the air brake system.
Immediately determine the availability of the rapid responder.
Close the angle cock on the rear car of the portion attached to the lead locomotive consist.
Answer: Immediately secure detached portions.Feedback: When a train separation occurs, the detached portion must be secured with hand brakes before repairs are made or the air brake system is recharged. Never depend on the air brake system for securement because the air can bleed off the cars. This would cause the brakes to release. Any increase in brake pipe pressure can also trigger a release.
