The classic one is Pau to Canfranc, most of which, apart from the stretch from Pau to Oloron Saint-Marie, was basically left to rot after an accident in 1970.
The tracks and structures being left in situ must surely have helped the case with the subsequent reopening from Oloron to Bedous in 2016, though of course practically everything had to be ripped out and replaced, right down to new ballast.
Ah! I am glad that someone has at last been able to cast some light on my question. Thank you.
So, after almost a month, the Forum has been able to come up with just one example out of numerous French closures, which took over 45 years to bear fruit and with no real evidence of the actual cash implications. This hardly sounds like a complete vindication of French policies.
I fully support protection of
alignments, such as Walsall-Brownhills-Lichfield, that might have scope for strategic re-use, but as East-West Rail has shown, simply leaving rusting rails on rotting sleepers in flooded cuttings between Bletchley and Claydon is of minimal benefit.
