Select the radio button for the scale of your railroad. This will be used in calculating scale feet when you enter actual inches. Select the scale you are modeling. This is useful when you enter the length of cars and tracks. You can enter the number of actual inches and the program will convert to scale feet. Append a double quote to the length when entering actual inches. The program will also automatically assign the proper NMRA weight for a car based on scale and length.
Maximum Train Length(ft)
This field provides the maximum default train length between cities. Later you can override this length if you wish a shorter train between any two locations. A 1000 foot train can carry approximately 20 cars, and is of course dependent on the car lengths assigned to the train.
Maximum Locos per Train
Now set the maximum number of locomotives that you want the program to assign to a train. If you don't want the program assigning engines, set this value to 0.
Switch Time (minutes) Travel Time (minutes)

Enter the average number of minutes it takes to drop or pickup a car on your railroad. Then enter the average amount of time in minutes it takes to travel from one location to the another.
