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. This is the default displayed line duration.
• 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. You can view the non-loop duration by hovering over the duration in the Lines editor.

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.

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.
