Yes , I can understand the logic of the above from a traffic operations 
perspective in that a double track line is a hell of a lot easier to operate 
than 2 X single track lines.
What doesnt make sense though is why wasnt Albion to Jacana simply 
dual guaged, ie the same as Sth Dynon to West Foostcray Jnctn.

the dual line double guage option would have not required either Macintye or 
Tulla loop to have been built.
I guess such decisions are lost in history.
