Restricted speed requires the crew to keep a lookout for which condition?

Explanation:
Restricted speed requires you to be able to stop within the distance you can clearly see ahead and to be prepared to stop for any obstruction or defective condition on the track. The most critical hazard to watch for is a broken rail because a rail that’s fractured can fail suddenly under the train, creating a derailment risk that you must be ready to stop for immediately. While fallen trees, damaged signals, and uneven ballast are valid concerns, they don’t present the same immediate, on-track failure risk that broken rail does when you’re operating at restricted speed.
