I remember reading about the Airtrack proposal.
I don't know the Staines area well enough,
but,
when out bikesploring with a younger mespilus jr. we found another long abandoned railway line just east of the M25, that is now a linear nature reserve,
and,
riding in along the (old) London Road from the A308 towards the pedestrian zone,
I'm certain we cycled under an old railway bridge, that forms the western boundary of the 'new' courtyard shopping centre.
Always wondered why that could not be used to get a railway line over the A308, then run parallel to Stanwell Moor Road to Heathrow.
Over the years the poyle line has been mooted as a connection to reading and the West.
There has also been plans for a connection to staines called the airtrack. Unfortunately that was shelved because of all the level crossing around various areas which would remain lowered for longer.
The latest idea is a spur line from feltham towards Hatton cross and new station for bedfont.
