At the end of the Long Fill, the track entered a rock cut and then passed into the woods and approached Peachtree Jct. Although the diesel locomotives would operate without having to refuel, steam locomotive #1501 was required to stop to add coal to the fire as well as water to the boiler. This was done on the loop track. Due to the construction of #1501, this stop was necessary, and could not be performed while the train was in motion.
