How loud are current freight trains? I'm imagining many folk are 'picturing' the sound of trains of scores of coal wagons clunk- clunk- clunking through the night. Maybe even the sound of marshallings of numerous trains, maybe train couplings tightening, clanking ...
I'm recalling picnicing at Didcot Railway centre and a train (ok a passenger train) just gliding by on the Avoiding Line without disturbing us at all!
Perhaps folk would prefer overlooking a line bounded by permanent continuous high fences (like the M25) rather than an occasional 'train in the country side'.
And that's without the 'environmental benefit' of less traffic on the
toads roads
