There is a small platform and a railing for the conductor to hold on to as this oil train makes a reverse move on the main at Rocky. The conductor is ensuring the track behind the track is clear, and that the train has a signal out the east end.
After the tail end of the train in on the main just east of Rocky, the conductor will get off the last car and the train will continue to back up without any protection under General Code of Operating Rule 6.6. This rule allows for unprotected reverse movements in CTC when the train will not pass a control point or grade crossing (among other things).
