Bidirectional train line actually, but still interesting to me. I puzzled in my head about this express train line and how the system works, and I did work it out, later confirmed by Wikipedia.
It will be hard for left hand car drivers to imagine, but never mind. Here is my best effort.
I journeyed from South Yarra Station to Mordialloc Station on the Frankston line, in house known by a customary three letter abbreviation, in this case the FKN line.
It was such a slow trip and not even vaguely competitive with car travel times and that makes me sad. Stations are close and the train stops at them all. Given there is a train every ten minutes, maybe every second train could only stop at major stations? But that would upset things as the line continues on from south eastern suburbs to western suburbs via the city.
While it made no difference to on time running, the older Comeng trains have such slow acceleration compared to the newer Siemens and Alstom trains. I was on a Comeng out and a Siemens in.
So there are three tracks and in the middle of the day the far left on the outbound side is unused. In evening peak times when express trains operate, I would think it will be used by the express trains, overtaking the stopping all stations trains.
But what about the morning peak when inbound express trains run? There isn't a separate track on the inbound side.
The outbound stopping all stations train uses the left hand outbound express track. The inbound stopping all stations uses its usual inbound track.
I was looking out the train window and sure enough, the centre track had signals in both directions, which confirmed what I was thinking. The inbound express train uses the centre track which during the day is the outbound stopping all stations tracks. The express line finishes at Moorabbin Station.
Yes, your eyes are glazed over but it is good for me to write this down and so hopefully remember.
And hey, you get a couple of photos of Mordialloc, a town severely divided by the major Nepean Highway. To note, the road did not seem nearly as busy as it used to be, possibly because of the opening of the M11 freeway and of course you know what.
Cannons at the ready near the war memorial to defend the sovereignty of Mordialloc.
