On up Torbay Express. This fine picture of D 825 Intrepid is actually at Coryton beach , with Coryton Tunnel in the background with Kennaway Tunnel just ahead and then with Dawlish being on the far side of that latter tunnel. The permanent 40 m.p.h. speed restriction board can be seen , that being the limit at this particular point at this period in time , such restrictions being eased over more recent years thanks to improvements in the track layout , but progress through the five tunnels still requires a reduction in speed , even today .
