You are running the lead locomotive pulling twenty empty coal cars into 3 East. Lynnbo is running the trail locomotive behind the trip. When you are done putting the empties on the section tipple, Lynnbo asks if you noticed the area of bad roof outby the firecar on the main line. You answer that you hadn´t, and you ask Lynnbo how bad it looked. Lynnbo said he thought that the roof looked ugly to him, but since he works in the shop, it all looks ugly. This is your section and you know it has been recently rebolted. However, you decide to look at it. You tell Lynnbo that you will follow him to the area in question. You must decide the safest course of action in determining if there is a problem, then you must decide the safest course of action to take in fixing, or having the bad roof fixed.
