A report into proposed additional rail routes to the vulnerable Dawlish railway line is due to be published by Ministers this week.
The analysis by track managers Network Rail detailing how best to avoid the route collapsing as it did this February - causing chaos and hitting South Devon's economy - is expected to be made public by the Department for Transport (DfT).
Early drafts of the report appeared to rule out reinstating the line between Plymouth and Exeter, via Okehampton, which was closed in 1967, it has been reported.
Creating a new line connecting existing freight lines from near Exeter and close to Newton Abbot had also been dropped.
Instead, the quango identified five 'new' route options – all starting on the outskirts of Exeter before looping at various degrees inland from the coast before connecting to the mainline again near Kingsteignton.
Even these more modest proposals would come with a hefty price tag, with one report claiming it could cost as much as £3billion, though Network Rail sources suggested they did not recognise the figure.
One suggestion is that ministers will agree to shore up the existing line immediately to avoid a repeat of this year’s carnage, and then complete a consultation on whether to carry out a much bigger upgrade before next April’s election - meaning the key decision will be for the next Government.
Mel Stride, Conservative MP for Central Devon, said: “I will continue to push for the Okehampton route – not as an alternative to a route to the west of Dartmoor but as a vital addition to support the economy of West Devon and ensure rail resilience for the peninsula.”
