Link above to comments on the awaited study, then follow link at bottom of that page to the pdf of the full 46 page study.
Figure 10 on Page 26 of the fast DAL options and Table 9 on Page 36 make interesting viewing.
Luckily there is total commitment to the Dawlish seawall/line whatever else is done.
One particularly interesting point in Table 9 is that Option 2, column 3 is quoted by NR as; Likely to be suited to continuous electrification.
Seems then that we could have our cake and eat it. i.e. properly beef up the wall/calm the waves and so pave the way for electrification along the sea front in the dim and distant future.
So good for NR to keep bearing this crucial point in mind and plugging it.
Still the small matter of £400m-£660m for Option 2
No views on what is potentially the most significant infrastructure investment in the SW since I don't know when, or is February 'so yesterday' now that the sun doth shine?
