Anyone know anymore about this? I'm just curious to know what has since been built on this once proposed route. This is from Wikipaedia. (my emphasis in bold)
"The Dawlish Avoiding Line was first proposed in 1933, to avoid the high cost of maintenance associated with the SDR sea wall, and keep the Exeter to Plymouth Line working.[1]
But in 1935, Chancellor of the Exchequer Neville Chamberlainproposed establishing an independent special purpose vehicle finance company, backed by a government loan guarantee limited to £26.5million. This could then be drawn down by any of the big four railway companies, with the GWR allocated “eleven fifty-third parts” to support the projects it had submitted for inclusion in the agreement, all of which had to be completed by 1 January 1941. Under the 1935 Finance Act, the GWR initially submitted just one proposal in the Treasury agreement (First Schedule, Part 1, Clause 2) which read: “Construction of a new deviation line from Dawlish Warren to Newton Abbot”.[2]
The proposed 16 miles (26 km) 1933 scheme within the two draft 1936 bills, diverted from the existing line south of Exminster. The scheme then went south through Kenton to Dawlish about 1 kilometre (0.62 mi) inland, then heading southwest underHolcombe Down avoiding Teignmouth, before rejoining the existing line to the east of Bishopsteignton. It was costed at £3M, and included three short tunnels and one long tunnel of 2,624 yd (2.399 km).[1] Parliament passed the Great Western Railway (Additional Powers) Act 1936, in which DAL is cited as “Railway No 1” amongst several listed.[2]
However, the GWR to enable other schemes developed a shorter route. This scheme of 8 mi (12.874752 km) deviated from the railway bridge over the Hackney Canal near Newton Abbot, and re-joined the main line at a point 62 chains (1.2 km) north of Dawlish Warren towards Cockwood, alongside the River Exe. However, in 1937 the GWR returned to a scheme closer to the original, called "Railway No 2”. Adding a further 7 mi (11.265 km), it commenced at the same point south of Dawlish on the initial deviation route (authorised earlier by the 1936 Act), terminating close toExminster at a junction 5 chains (0.10 km) south of a bridge carrying Milbury Lane over the line.[1][3][2]
Construction[edit]
The GWR started construction in Spring 1939, with surveyors poles in place along the proposed route by the summer. However, after the outbreak of World War 2, all work stopped.[1][2]
Work was never restarted, and after the post-War nationalisationBritish Rail sold the purchased land. The powers of the associated Act of Parliament lapsed in 1999.[1]

that living in West Cornwall I may have a slight bias of opinion about speed and reliability though.
