Thank you, exactly what I wanted to know!Passenger rains ran past Fremantle Many years ago, I'm guessing 1940's, to at least South Beach, not the closed station there now but around where the park is. There also used to be trains running from Kalamunda to South Beach as sea side excursions, I have seen an old photo somewhere. The only other time passenger trains run past Fremantle was during the America's Cup, or again excursions. Link.
Did frequent suburban services on the Fremantle line originally continue south towards Coogee etc or did they always mostly end at Fremantle?
There's an extract from a 1989 Armadale Line timetable included at 10:55 in the following video:Just watched the video. Brought back some memories. A lot of changes since then, especially around the CBD and foreshore.
Basically there's a train approximately every 7 minutes at peak (split across two stopping patterns, similar to the Fremantle and Midland lines today) and every 20 minutes off peak, with a limited service at night.
The Midland (or Bellevue as it was at the time) and Fremantle lines ran a similar 20-minute frequency upon dieselisation in 1954, but Armadale (according to Rail Heritage WA's Marble Bar to Mandurah book) languished at 40 minutes until around the 80s when the Fremantle line was closed.
