Keio Line 7000 Series Train Entering Tunnel
Three tracks of Keio Line’s quadruple tracks enter a tunnel at the west. The spot is shown in “Keio Line Trains Part the Ways at the East of Sasazuka Station.” The other one track goes on the ground for a while, and enter the tunnel here.
Map tells that the two tracks at the center turn and go under this track. It should be the reason why all four tracks could not have the entrance at the same spot.
