Transperth Trains B-Series EMU (Batch 2) - Leederville to Perth Underground (Joondalup/Yanchep Line)

[@sgbuses]

They are stopping patterns. During rush hour on Fremantle Line for example, some trains will run all stops to Claremont and then express to Fremantle, while others non-stop from Subiaco to Claremont and then all stops to Fremantle

why do some trains say perth b or perth a or things like that?

[@armadalegarbo]

stopping patterns, meaning some skip stations.
