A 7-car S stock will not fit into the bay platform at Putney Bridge. They will have to reverse past the station like D stock has to at the moment. Wouldn't it make sense to rebuild Putney Bridge by either removing the bay or the WB track, so there is a wider platform, and have a crossover at each end of the station, so that S stock could reverse in the WB platform?

TBH, and this has been mentioned several times quite sagely by tubeprune, the issue of signalling berths for S stock is network-wide...........
I guess the Signal Dept. are beavering away at solutions.

What would be nice is to use platform two as the through platform and have the higher speed approach and no longer use the current westbound platform.

This has indeed been covered before - the solution (probably now subject to available funds) is that the current bay (p2) will become the Westbound through platform and the current Westbound through platform (p3) will become the bay.

Thinking ahead to when Chelney shares the route, is it not possible to make the current bay platform long enough for 8 car trains by altering the trackwork? I can't confess to having gone that far south on the Wimbledon branch.

If the platform swap I mentioned above goes ahead (which covers part of your question), there'd naturally have to alterations to the track layout.

It all seems a lot of cost when there is easily a good reversing point a stop up the line at Parsons Green where it would be cheaper to modify?
What about East Putney?

East Putney has a ground frame and is operated under Network Rail rules - absolutely no good for routine reversing.
Whilst Putney Bridge is only one stop further up than Parsons Green (and one stop further for the punters), the methods used to reverse are very different. As mentioned Putney Bridge uses a Bay (C stocks only mind!), and with it currently being a centre job, it's use only causes a delay in the direction the train is traveling. Even if it does move to one side, the delay it causes wouldn't be as bad as trains that reverse at Parsons Green.
The reason Parsons Green is more of a pain is that it only has sidings, so each train causes a delay whilst it's tipped out in the platform, then another when it comes back out and picks up passengers again (though the latter isn't an issue from 21 and 22 roads as they don't pick up at Parsons Green on account of not being fully berthed in the platform - one of the many reasons that actually makes Parsons Green the most complicated area on the District!).

Fair enough, but perhaps it could be modified at less cost? Forgot East Putney was NR! Will the sidings at P Grn be able to take S7s?

Some of the sidings will need minor work, such as adjusting the walkboards and trip arm locations - but 29 road (the one behind the Westbound platform) is a C stock only siding with no room for expansion....

Pleased to say the restoration of BEA coach MLL738 is as complete as it can be, now restoring MLL721

I would imagine that is down to a combination of lack of staff (the station has One Station Supervisor, One CSA (sometimes) and one SAMF (ticket office), and perhaps a lack of information from service control.
On the days where we've been booked to terminate there recently, because of weekend engineering works, I have been tipped out by the Station Supervisor - but if it's an ad-hoc turn, it really depends on the Station Supervisor being told and whether or not they or their staff are available.

Perhaps something akin to a help point could be installed for TOps use when they have to tip out. Some sort of hard wired radio into the ticket office?

If they know the number, they can call them on the radio.
