This recent consultation and the discussions provoked by it have convinced me to switch my preferences from the Camberwell route to the OKR option - the opportunity to serve New Cross Gate and gain interchange with the BML is too good to miss, even if it does mean missing out on interchange with the SLL at Peckham Rye or Queens Road Peckham...a shame though.

As for beyond Lewisham...I am still firmly of the opinion that Hayes is completely the wrong option. The route will need vast amounts of new depot capacity, and there is nowhere with the land available on that route. Taking over the surface line from Lewisham to Beckenham via Catford also removes a very useful bit of mainline railway from the network.

No, if you were desperate to remove the Hayes line from Lewisham, then I think the solution is a short tunnel under (through?) South Norwood Country Park to the underused line through Crystal Palace. Perhaps a new station on the BML slow lines at the interchange, though I suspect Crystal Palace would suffice. Both rail lines heading to Beckenham could then be given to the trams.

My preference is for the new tunnels to continue slightly further past Lewisham - through Blackheath - and surfacing past Blackheath Junction. The line then would take over the Bexleyheath line through to Slade Green (expansion of which would give the depot space required), then diving back into tunnel to serve Dartford (so adding more capacity on the lines into it from the west), then heading south east to terminate under Bluewater (adding a major traffic generator to the end of the line to generate contraflow traffic)..
