Training District drivers on the route would be a simple (although not necessarily quick or cheap) thing to do if it was seen as desirable to stable that line's trains there regularly. The other factors though rather suggest that these sidings won't be compensating for Lille Bridge.

Have there been and will there be any tours of the depot for the public before its demolished?

I wonder if the LT Museum could do a Hidden London tour of the 150 years of history, back to the steam days of the District Line and also the opening of the Picc Line.

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

S stock is not allowed on that route at present. South Harrow sidings will be needed along with the new Picc depots to accommodate the full fleet of new trains for 36tph once new signalling is installed on the line. The current fleet order is only for 30tph, which will still need new signalling to achieve. District crews are not trained on the route, but could perhaps have a Picc line pilot if S stock was ever passed for that route. After thought, the new sidings have boarding platforms which might foul the surface stock gauge. May I refer you to a pot on here many years ago from contributor 'PiccadillyPilot" who wrote an amusing article about a district train taking a wrong 'un at Hangar Lane. I think the original was lost when the site was "modernised" a few years ago.

There’s this story on Tubeprune’s site of a Piccadilly train taking the wrong stick at Hanger Lane Junction. The passengers were duly sent back to get the next Piccadilly train, which did exactly the same thing!

The other factors though rather suggest that these sidings won't be compensating for Lille Bridge. The same thing happened when C77 stock arrived for the Wimbledon branch. Could District crews work them to and from Hammersmith Depot? No way! That was Met crew work. So awkward crew changes had to be arranged at Edgware Road, especially to deal with defective train changeovers. That was back in the old days. But what happens today, when the situation is reversed? Nothing changes! To get a Hammersmith train changed over at Upminster, a District driver has to take it over at Barking. The same for Circle trains to get to and from Ealing Depot. So training District drivers for South Harrow sounds simple, but I doubt it would be so. There is also the unknown unknown of Piccadilly Line resignalling which will need to be compatible through Acton, but if that is costly then may not be installed through to Rayners Lane since S stock is not approved for the route currently.

Heading off at a tangent slightly, wouldn't it be sensible if the new Picc signalling was the same as the District line? Or perhaps reasign the Rayners Lane - Uxbridge branch to the District line, although there proabably wouldn't be enough trains for that?

Technology always moves on, hence why the Northern and Jubilee TBTC is slightly different to the SSR CBTC and trains are not compatible.

E.g. link Quantum train location testing on the London Underground may be available for Picc in 5 years.

Looks like a brilliant idea but can anyone give a layman’s explanation of how Quantum Train Location would work? The article says it doesn’t rely on trackside equipment or satellite location, but doesn’t say what it does depend on. Edit: A second read says sensors are being developed, which if they can be made to work reliably, would “infer the strength and direction of the earth’s magnetic field, which can be compared against mapped data to identify a train’s location”. Hope I’m getting this right

In addition to Dstock7080's post, there are also potential concerns about reliance on a single supplier and market share.
