>>1982312i suspect HX will probably change into an alternating Old Oak Common / Paddington service once Phase 1 opens (sad, empty, hollow lol), but that'll be about it as far as transport from Heathrow goes, for a long, long, long time. simply because you can't have both net zero 2050 _and_ expansion at Heathrow.
the western rail link has been kicked about for decades, but in a world where the absolute worst-case alternative is having to double-back at OOC via HX or Crossrail, i don't think it'll ever happen.
