The assumption is of course one lot of ... equals one station. Ain't necessarily so.
Remember that route is the only line in Melbourne where there's more than one way to get to the terminating location. When an express run is loaded into PRIDE, Seaholme Altona and Westona simply don't exist at all, because it's a different run.
The two lines are simply spacers designed to fill up the screen, nothing more.
Everywhere else, it's different. The ... does signify a missing station, because it's the same run - say a down Belgrave SAS versus the down Belgrave express versus the doen Belgrave "Puffing Billy special"
The route is the same but stations are deleted from the PRIDE listing to comply with a specific runs stopping conditions.
I don't believe thats correct, the "..." indicates a skipped station. Two "..." means two skipped stations.
In this case it indicates that Paisley and Galvin are skipped.
I don't believe its just to fill the screen, it doesn't work like that anywhere else.
