Redesign of platforms between BTM▸ and Weston to take 5 carraiges at each station AND (probably more critically) so that exits aren't just at one end. E.g Yatton & Nailsea, carraiges close to the single entrance are busy while those further away aren't.
Hmm. With thanks for your suggestion, initiation, I'm not sure that it's worth the cost of building another entrance / exit to the 'up' platform at Nailsea & Backwell. And while it would be great to have a second, preferably ramp access on the 'down' platform, that seems to have been swallowed up in the abyss of 'there is no funding for such developments'.
New station at Long Ashton, but to achieve this I think we need passing lines at stations to avoid slowing down the long distance trains.
There
used to be a station at Long Ashton, but I can't see any case for that being reinstated: the 'park and ride' at end of the new South Bristol Link road is ... erm, just across the road.
My personal preference is for a re-opening of the station at Flax Bourton - but that turned out to be an
April Fool story.
