When a train is required to operate through a flooded area with water covering the track, the conductor and engineer must:

1. Proceed at normal speed since modern locomotives are waterproofed
2. Assess the water depth, check for track damage, and if authorized to proceed, do so at the specified restricted speed
3. Stop and wait for the water to recede completely before proceeding
4. Operate at 25 mph to minimize the time the locomotive is in the water
