Following a recent flurry of correspondence between myself and MRFS I've finally acquired enough information to complete a set of diagrams showing the Western end of the Central Line at the time of the extensions to Greenford and West Ruislip. These compliment my earlier diagrams of the eastern extensions of the Central Line.

Well done Harsig, I didn't realise there were so many changes in such a short space of time......

Excellent work! Quite amazing! I would be interested to know how the connection to the GWR/WR Up Relief I think it was (not Up Slow?) was tied in to the Central at Ealing Broadway, just to the east of Hanger Lane bridge.
As an aside, being interested in the subject, is there any known draft of the proposed signalling etc. for Denham?

Denham and Harefield RoadI've not come across any; but then again I've not been looking too hard. However, given what is known about the plans for the services out to Denham in the New Works plans, I would put in a fairly strong suggestion that the following would be the most likely: - EB 'X' for West Ruislip would be CSX. 257, Harefield Road EB starter.
- WB starting signals at West Ruislip would be from the range 20-23 inclusive; points would be 10 - 11 for a scissors crossover on the main two platforms.
- If the unused third platform were to be connected westwards, then the lever 15 would be used, being spare at the time of opening. I suggest that the third platform being connected would be unlikely a) as there is a new works precedent for the terminating siding - Edgware b) 15 is at the wrong end of the block allocated to the points; if 15 were used there would be some counter-intuitive lever moves by the signalmen.
- EB home signals would be from the range 1 - 4
- Harefield Road would have the EB home A 255, most likely just a single head rather than A 255A and A 255B, based on the assumption of 6tph peak and 4 tph off peak. WB signals would be A 256, A 258. For the purposes of sane reasoning I would suggest that the goods yard was shut (there is a surprising amount of evidence for the rationalisation of some goods yards in the New Works plan).
- Denham itself would be quite close to Alexandra Palace in layout. The signalbox would look after the scissors crossing and terminating LT traffic in a two platform station but with either junctions before the station (if the Central was overlaid on top of the existing track with no separate permanent way) or just a straight standalone terminus if the Central had its own right of way. I suspect too, that Denham would be code 'CU', leaving 'CT' for Harefield Road if necessary.
Of course, these are just idle musings and don't necessarily have any basis in concrete evidence. ;D ;D What is known though, is that the train description 'Denham' could be set up much further east - 'ABC' from memory, I think. Ealing Broadway and the GWR connection.As I've already put on the site here, the diagram for Signalbox 'L' Ealing Broadway and I've just uploaded Track Circuit Diagram (coloured) shewing the slotting arrangemetns with the GWR box and the Down Relief, from the map for the opening of the E&SB. However, all this is rather diluting Harsig's fabulous efforts.

Didn't Wood Lane loop have a platform face on both sides? I could have sworn I've seen that in photo's.

Yes it did, until the Ealing extension rather inconsiderately went through the middle of it.
MF 47 6.46 [8] out as 4 7.30 31 7.6 [7] out as 3 7.12 64 11.58 [7] out as 2 6.15 32 12.28 [7] out as 1 5.37
Sa same, but [8] is 10 1.31 and [7] after is 41 2.7
Su only [7] in service at 7.43 and 17 out 10.32
All Wood Lane starters, apart from 64 which is Hainault; 8 car MF starter stables Queensway MF.
