The diagram presents two station configurations. The first configuration is labeled Stub-End Terminal with Adjacent Regional Metro and shows six platforms connected to tracks that end at the station. Below it, a separate metro track pair is shown with two platforms, one on each side of the tracks. The second configuration is labeled Through-Station with Adjacent Regional Metro and shows six platforms connected to tracks that continue through the station. Below it, a separate metro track pair is shown with two platforms, one on each side of the tracks.
