After passing through the 47yd Wrangaton Tunnel the line passes through the remains of Wrangaton railway station; Monksmoor Siding on the right used to serve a naval stores depot.
The line swings left under the Marsh Mills Viaduct of the A38 road and then runs alongside the tidal estuary of the River Plym on the left, with the grounds of Saltram House at Plymstock on the far bank.
