|picking up empty coal train at power plant|
The coal mine and power plant are connected through the hill. Loaded cars are picked up from the rear track of the mine as a unit of say 12 cars. When this east bound train arrives at Heron,s Landing it is backed into the rear track of the power plant, pushing most of the cars through the hill so that they are ready to pickup from the coal mine.
Empties are then picked up from the front track of the power plant as a unit of 12 cars. The train will head east bound through Heron's Landing, proceeding through the reversing loop and then head west bound arriving at Valleyview. The engine is run around the train and the cars are then shunted onto the front track of the coal mine, pushing them through the mountain until a few cars are in front of the power plant.
The engine is then taken to the round house for servicing.
The short siding at the power plant is for special deliveries only. The short siding at the mine is for deliveries and individual coal hoppers that are subject to the normal card system routing.
At no time is a locomotive run through the hill!
