The pattern of car movements now begins to become clear. A specific car is in Bethlehem. The Yard Master there decide that this car should go to an industry in Jim Thorpe. By consulting the switch lists, he decides that because of the type of car, it will go to a particular industry. Depending upon which way that industrial spur faces, thus determining which direction of train it is easiest to switch the car from, he routes the car either directly to Jim Thorpe, or to Wilkes-Barre to be brought back to Jim Thorpe.

If the car goes first to Wilkes-Barre, it should be delivered the next "day". The idea of having the cars lay over in Wilkes-Barre "over-night" is to eliminate any problems of "tight connections," since the movements of a drill will take up most of an operating session, or "day". However, there is nothing to prevent a second drill being run, if these is sufficient traffic to warrant it, and there is a crew available to operate it. But to keep things simple, the general rule is, a car make one trip in a train per day.

Leaving Bethlehem, the car will go west to Wilkes-Barre in a day, come east to Jim Thorpe on the 2nd day, lay over a night at the industry, and take a day to come back to Bethlehem. The sequence of movement will vary according to how the car is most easily switched. But at best, it will take 3 days to get this car back to Bethlehem for another assignment. It may very well be sent somewhere else after the delivery, or even misrouted or delayed. Thus the period of use is varied, and with more cars, the variety of the pattern is assured.

How should the crew keep track of where a car should go, since another crew may complete a delivery started previously? As with any system, rules and reminders are necessary. Since this is for fun and not for actual business, we should eliminate as much paperwork as possible. The rules should be simple, logical, and easy to remember. The reminders should also be very simple, and kept to a minimum. The system itself should be flexible, so that when someone wishes to "just run trains," he doesn't make the system unworkable for somebody else.
