Riviera Line - Infrastructure

Infrastructure

Trains going towards Paignton are described as travelling in the "down" direction; those towards Exeter in the "up". The line is double track throughout except for a long single-lead junction at Newton Abbot where trains are turned off the main line onto the Paignton branch. Loops at Dawlish Warren allow slower trains to be overtaken, as does the flexible layout at Newton Abbot where all three platforms can access the Paignton branch. At Exeter St Davids, Riviera Line trains generally use platforms 1 and 3 as these allow access to and from Exeter Central and the Avocet line; starting or terminating trains may also use platforms 4, 5 and 6. At Paignton down trains may arrive in the up platform; if they arrive in the down platform they must shunt across to the up before departure, generally via the sidings at Goodrington Sands.

Between Exeter and Newton Abbot the predominant speed limit is 60 miles per hour (97 km/h), the route availability is RA8, and freight loading gauge is W7. On the Paignton branch the predominant speed limit is 40 miles per hour (64 km/h), the route availability RA6, and the freight loading gauge W6A. Multiple aspect signals are controlled from the panel signal box at Exeter and allow a headway between trains of four minutes from there to Newton Abbot and seven minutes onwards to Paignton. The sea wall section is signalled for trains to run either way on the up (landward) line to allow for restricted working in the event of sea damage to the down line.

The Paignton branch has been identified as a "fragile route" where the addition of any further loco hauled traffic would have a significant impact on the residual life of track and/or structures. The three stations on the branch are currently under consideration for the provision of improved facilities but this is dependent on third-party funding being made available.
