Will the Lords be able to amend the bill so that Reading, Ebbsfleet
and possibly Stansted become the logical termini?

As I understand it, the Lords may amend (or reject) any
Commons-originated Bill except a Money Bill (the Budget, in effect).

If the Lords amends a Bill, those amendments must be approved by the
Commons before Royal Assent can be sought.

Should the Commons disagree with Lords amendments, the Lords then can
either withdraw them, allowing the Bill to go to RA; or it can insist
on them, possibly resulting in a game of Parliamentary ping-pong.
