The duration of a line is how long it takes a train to run the line from its start to end. The game has two related duration concepts:

• The "loop" duration includes the time it takes the train to travel from the last stop back to the first stop. It is useful if trains run (continuous) line loops.
• The "non-loop" duration excludes the time it takes the train to travel from the last stop back to the first stop. It is useful if you use complex manual orders that have the same trains run different lines in succession.

Calculation

• Line duration in the line editor is estimated by the game by running a phantom train on the whole line. Sometimes this estimation is off compared to the real outcome.
• If the first stop is not the last stop, the duration in the line editor does not include the travel time from the last stop to the first stop. The timetable of trains using the line will account for this time, however.

Custom durations

If you want to avoid trains making very long stops around 6am (or your custom time) for 24hr services, your line duration must be a factor of 24 hours (1440 minutes) so there is no remainder time to make up before the line starts again. The custom duration feature of the line editor automatically finds an optimal line duration for 24h, 7d or any desired custom period of time.
