Which situation allows placing the entire train in emergency despite air blockage?

• A. It is impossible to place in emergency
• B. You can still place the entire train in emergency
• C. Only the front portion
• D. Only if the EOT remains connected

Answer: (B)

The main idea is that an emergency brake command is meant to affect the whole train, not just a part of it, even if there’s a blockage in the air line. When you trigger emergency from the locomotive, the brake system is designed to propagate a rapid brake signal along the train and cause all brake valves to apply. This means the entire train can be brought to a stop despite some section of the air line being blocked. The action does not rely on the End-of-Train device being connected, and it isn’t limited to the front portion of the train. So you can still place the entire train in emergency.
