ALTERNATIVE rail lines to the storm-hit coastal route through Dawlish in Devon, including the re-opening of the Okehampton to Tavistock line offer 'poor value for money', according to a new Network Rail report published in Tuesday. The alternatives considered Route A - the former London and South Western Railway route from Exeter to Plymouth via Okehampton; Route B - constructing a modern double track railway on the alignment of the former Teign Valley branch line from Exeter to Newton Abbot; Five alternative route Cs (C1 - C5) — providing a new line between Exeter and Newton Abbot. Each route was appraised according to where the project benefits and costs ratio (BCR) measures the net economic benefits per pound. Schemes with a BCR of greater than 4.0 — £4 of benefit for every £1 spent — are deemed to be of very high value for money, while schemes with BCR of less than 1.0 are considered poor value. Route A, the Okehampton route, offered a BCR of 0.14 — the other routes ranged from 0.29 to 0.08 and 0.17. A Government decision regarding the rail network is expected later in the year.
