Just curious.
Sub surface lines plus Bakerloo seem to have been left out of things.
Can't see any reason for there not being at least a partial service as on the Central Line.
Met: Baker Street-Harrow On The Hill (possible one per hour further north)
H &C: Hammersmith-King's Cross only (no Circle Line service)
District: Ealing Broadway-Barking (Bus connections to Upminster)
Bakerloo: Harrow & Wealdstone-Waterloo (Bus connections to Elephant)

All of these lines use much older signalling control systems, and haven’t had the same level of investment as those that do run Night Tube (Piccadilly excepted, which is a special case).
In terms of the SSR there are currently significant weekend and overnight possessions for the 4LM signalling control upgrade, the next part of which is due to go live next weekend. Until this upgrade is completed it would not be possible to offer any kind of reliable Night Tube service as happens with other lines - the alternative of course being weekday closures.
A service on the SSR is planned from approximately 2022 onwards, initially around the Circle line but later on the District and Met too.
The Piccadilly will have all this in years to come once it’s own signalling upgrade begins. The main reason it runs at the moment are for links to Heathrow and through the West End.

Just a guess, but it may be difficult to run a night service on the Bakerloo without access (over NR tracks) to Stonebridge Park depot

Are you sure about Queen's Park, I thought that was Network Rail too. |

Carto Metro shows that all the sidings except the western (northern) end of 21 road are the LU side of the boundary - and it wouldn't surprise me if that part of 21 road is mainly there to provide a bufferstop for trains that SPAD the junction signal.

aslefshrugged and Chris M , you a both kind of correct as part of 24 and 21 roads fall on the NR side of the boundary. On the NB, signal WS 13 sits on the LU side protecting the last parts of the road including the turnout and overrun. On the SB signal BB1 also sits on the LU side but is just after 503B points which are trailing trap points on the NR side.

Even if use of the north sidings was an issue, the infrequent night tube service could be comfortably reversed in the platforms at Queens Park.

District: Ealing Broadway-Barking (Bus connections to Upminster) A night bus service to Upminster? Now that would be very welcome. I won't hold my breath though  |
