Obviously the S stock will need to be passed to carry passengers in service everywhere on the Met, District and H&C. Are there any plans to allow them to run to any other destinations in passenger service in case of service disruption/wrong sticks/etc, e.g. Northfields and Ealing Common-Rayners Lane? What about the East London Line?

Acton to Northfields & Ealing Common to Rayners Lane are mere rumours - there are no firm plans of any sort. That said, the former has a test track, and the latter is used for stock transfers - so who knows what might occur  The East London line will not be part of LUL - and will use different traction current arrangements, so it's not all that likely. |

the S stock will be smaller than the A stock, i believe so they probably would fit.
but that is beside the point really as Over heads are being put on the ELL i think.

When the ELL leaves LUL, the physical connection to the District line at St. Marys Junction will be removed.

I was told during a presentation that it would be retained, but without any form of electrification.

If rumour is to be believed, compsci is correct

Sensible IMO. Retaining it would provide another delivery route between the Underground and National Rail, for materials or for rolling stock.

When were the connections at New Cross and the Gate with the Southern Region removed?

If retained for such, would it remain double tracked. I have been told that two trains cannot pass on the double tracked curve anyway, and keeping just the inside track would eliminate the maintanence on two cross-overs.

There are no restrictions that I know of there.

I have been told that two trains cannot pass on the double tracked curve anyway, and keeping just the inside track would eliminate the maintanence on two cross-overs. The prohibition you are thinking of applies only to A stock. The signalling does not permit two trains to occupy the curve at the same time, and since the curve would probably never be used in a situation where two trains would need to pass on it, it does not pose a problem for any later use. Besides, there are no crossovers at either end - both junctions are standard double flat junctions with diamond crossings. |

My apologies - by cross-overs I meant diamond crossings which are quite expensive to maintain.

Would it not be a good idea to reinstate a physical link to Network Rail at Northumberland Park for stock transfers on and off the Victoria? The 2009 stock will not be able to use the Piccadilly to get to Ruislip via Finsbury Park and Acton.

they will all be delivered by road for economic as well as practical reasons. They won't fit down the Picc so it is the only way.

St Mary's Curve - have just looked up the standards. The restriction on one train only at a time on the curve applies to all stocks and is due to limited clearance between the tracks.
Due to the limited use, I can't see any point in replacing the existing arrangement with a single track, as this would require relaying and resignalling the junction so as to permit the single track to gain access from the eastbound and to the westbound District. (and such works would require a possession over the running lines of the District, H&C and probably East London.

That's because the they moved the tracks inward because the A stocks would otherwise hit the tunnel walls. If the track was in its original configuration it wouldn't be a problem. Due to the limited use, I can't see any point in replacing the existing arrangement with a single track, as this would require relaying and resignalling the junction so as to permit the single track to gain access from the eastbound and to the westbound District. (and such works would require a possession over the running lines of the District, H&C and probably East London. Indeed. It's still useful as a double track curve, and clever timetabling can ensure that any later usage once the ELL goes over to NR is appropriately restricted. |
