The clock advances minute by minute on the screen until enough time has passed for the first play to end. The label bearing the play's title and the large dot disappear. A small dot, representing a moving wagon, begins to move from the first station to the next station. The computer then instructs the second play to begin performing at the first station. When play 2 finishes performing at the first station, play 3 moves into place, and play 2 begins its journey to the second station.
New plays join the procession as space opens up in the first station.
Vintage computers with sluggish graphics chips may slow down noticeably when many wagons are moving at once. The varying time required to update the graphics has no effect on the numerical results of the simulation, however. This section illustrates the data utilized by the non-Java version. The second number represents the Y coordinate with 0 at the top and 1 at the bottom. The third number, in minutes and seconds, represents travel time from the previous station to the present station.
