Hey, I recently noticed the release of the London Overground from Barking riverside to Gospel Oak. But what about the Elizabeth line? Now, I do know some people do the elizabeth line using the GWE map, but it would be cool to have a line from Abbey wood to Reading or Maidenhead, even Heathrow using class 345's. The stations would be: Abbey wood, Woolwich, Custom house, Canary Wharf, Whitechapel, Liverpool Street, Farringdon, Tottenham Court Road, Bond Street, Paddington, Acton Main Line, Ealing broadway, West Ealing, Hanwell, Southall, Hayes & Harlington, West Drayton, Iver, Langley, Slough, Burnham, Taplow, Maidenhead, Twyford and Reading. The line would be nice as it has Inner london Outerlondon and Greater london.
The western segment, whilst already present on GWE, would require a near total rebuild as major changes to the route infrastructure have been made since when the route is set. Add to that how the core section has Automatic Train Operation (i.e. self-driving) which is very divisive - being a train driving simulator where you don't actually drive the train (just pressing a start button at every station). However, something like the eastern segment out of London Liverpool Street to Shenfield as part of a wider Greater Anglia route would be an ideal candidate, subject to licensing of course.
