A notable feature of Perth's urban rail network is that a significant portion of it operates in the median of freeways, with dedicated bus-train interchanges and extensive Park & Ride (P&R) facilities provided at certain stations.[2][3] Passengers arrive on feeder buses or use P&R and transfer to trains at train stations. These system design features are a response to Perth's low density.[2][4][5][6][7][8]
