The Adelaide City to Seaford railway line using the Adelaide Metro A-City 4000 Class EMU (pictured), or in the event of power cuts the old Adelaide Metro 3000/3100 class DMU with dodgy air-conditioning if you're unlucky... (Personal photo) The route is a mixture of urban, rural and coastal stops. It's a really nice commuter route in the morning and evening, especially when you pass through Hallett Cove Beach overlooking the sea.
