The Turtle Creek Model Railroad consists of a single track main and three branchlines with eight walk-around throttles.
Operation is based on car cards and timetables with ad-hoc dispatching.
There is a car card for every car. The cards are stored in boxes labeled for the industries and are moved by the operators when the cars are moved. The car cards have boxes printed on them where the operators record car moves. At each town, move any cars that are destined for other locations at the town. Deliver any cars in the train destined for the town.
