I picked this up from gizmodo the other day - 3D Map jolly good fun. Not too sure about the absolute accuracy of the movements, mind.

That is not the old signal cabin it is actually in the second picture where the brickwork is white on the lower half on the platform ramp. It is you know (but the old er signal cabin) - the 'topless' building is the old Whitechapel and Bow Railway electromechanical signal cabin that opened on 11/06/1902 - you're thinking of the LPTB power installation that opened on 20/10/1946 and demised as charted by reg. upthread

There is a subtle and fine difference between 'vigilant' and 'vigilante' - we're not talking New Cross (wink, wink, jk, jk before anyone gets wiggy).

I'm with reg. on this one; though I will comment that is seems very odd that nothing has come floating to the surface about Denham. Given the level of planning that I'm aware of for the Northern Heights and associated paraphernalia and that WB TDs for Denham could be set up (together with indications in some cabins and on some platforms) and the planning I've seen for other unbuilt termini I'm a bit more optimistic than reg. but whatever is out there, it is well hidden. I know the planned levels of traffic that would have gone to Denham, and I suspect that all there would be is a two-platform affair with one pair of scissors. West Ruislip operating Denham is an interesting question - on opening there were 4 levers at the 'right' (i.e. left) end of the frame spare, but the other spares don't fit into the pattern quite so readily: - 1 - 4 spare, 5 - 8 in use as EB signals, so 1 - 4 likely as EB signals too
- 10 - 11 spare, 12 - 14 in use as 'station area' crossovers, so 10 - 11 likely for western end crossovers
- 16 - 19 WB signals in station area, 20 - 23 spare so likely to be used for WB signals towards Denham
- 24 - 26 in use as EB discs, so spares 29 - 31 likely for WB discs
- well: the suggested functions of the blocks 16/19 incl. and 29/31 incl. may have been the other way round
- there were quite a few route setting functions spare, but at the 'wrong' (i.e. right) end of the frame
Based on that, I don't think Denham would have been controlled from CS at all until the telephone key type route setting came in about 10 years later. I also have a hunch that Denham would have been code 'CW' or 'CV' - CT and CU would have been 'strategic spares' for Uxbridge High St and Denham East/South Junction.

In this instance Acton Town S5 means suppressed - signals which are deliberately extinguished to avoid drivers being distracted during unusual moves - examples being: Mansion House EB to bay, Tower Hill EB to bay. Ahhh, so these are signals not on the route for the train, but a similar route nearby? Yes. Usually done to prevent a "read through" - long chain of green and in the distance is a red. As soon as the red is seen then on go the anchors. There's a good view of this in the old Central Line cab view.

Can anyone help I can not find anything on the reversing of trains over the cross over. When trains are running through normal without reversing are the signals associated with the speed control working normally or are the aspects out, the signals in question being; A1000 actually between the SB & NB on crossover-is the red aspect normally alight? Unless something has changed recently the red is normally out until BP 10 clears - I've seen that myself. I think also that keyswitch 'out' will illuminate it too. A9000 North of station on NB Do these work normally until a train reverse's SB-NB and then the speed control part is actvated? A9001 North of station on NB A9002 North of station on NB OK... AFAIK, BP 9 clears straight to green when 7 B normal, with 7 B reverse it'll clear to Y with the PD activated on the crossover. A9000 steps to Y with 7 B reverse and the PD near 7 B points picked, similar for A9001 but PD picked near A9000 and likewise with A9002 but PD picked between A9001/A9002. All these seem to only step to Y when 7 A/B reverse: so when the crossover is normal, they clear normally - from my notes the speed signals need to have the signal in advance at red to step R - Y but this doesn't apply when stepping R - G with 7s normal. Does that help? I think that there was an article in the UN about it a few years back after the third oowhoopscrunch.

Right then, I have a little clutch of Set Working books the early ones in my lot are indeed enumerated as 'Supplement to WTT' - I can lay my paws on the following: - Supp to WTTs 73 & 74: separate Sundays start 2/5/55, buff stiff paper cover
- Set Working for Weekdays and Sundays in operation from 17/6/63, green linen exterior cover, interior buff as above and identical wording in title page to above apart form calendric changes
- Supp to WTT No 91 in operation from 17/10/66, medium blue line cover, but wording identical to WTT 74
- Supp to WTT No 92, in operation from 16/10/67, dark buff linen cover, note 'UFN trains shown to reverse at Tower Hill will do so at Mansion House forming their schedule westbound workings
- Supp to WTT No 96, in operation from 7/2/72, light blue linen cover
[/i] [li]Set Working book No 3 31/5/75, medium green card cover, computer printed at 55 (29/4/75 at 20/37/59)[/li] [li]Set Working book No 11, 6/12/82, clarty green linen cover[/li] [li]Set Working book No 15, 15/5/89, medium green card cover[/li] [li]Set Working Book to WTT 127, standard green TT design[/li] [li]C stock Set Working books for TTN 11/99 and 12/99 (Covered Way No 58 works), standard H&C temporary colours on spine at double pitch[/li] [li]H&C Set Working book to WTT 23, standard H&C hatching[/li] [li]District Set working book to WTT 133, standard District design[/li] [/ul] As you can see there are several variations, Set Working book No 1 would have been for two [blocks of WTTs] before WTT 100 (M-F), WTT 101 (Sa) and WTT 99 (Su) - I'd need to dig around to find that date out, maybe tomorrow. I presume H&C books stopped at the same time?

Not quite, but yes in a way. Back in the day when there was divided working (coupling and uncoupling) it made sense, after that with the complex working on the District it was a good aide memoire - all it is overviews of stock diagrams organised by set number.
I'm not quite sure when the sequence of set working books started. Let me wander upstairs...

When WTT 89 came in on 12/10/64. It brought in 24h clock across the combine and the last remaining peak services to Hounslow West were withdrawn. No Picc stabling at Ealing Common and no District at Northfields.

I think at the moment, this thread is best locked.
For information, I will say that I raised the matter upstairs and there was a discussion amongst the Forum Staff.

I used to belong to the Croydon Tramlink yahoo group. I don't know if it is still going - I unsubscribed about a year ago as I was getting too busy to read it properly. Perhaps this forum does not need to duplicate it. I think it's certainly something to look at upstairs. I quite like the idea, given that myself and AI were on the LTM tramrailtour in all the snow last January. Croydon looked really pretty under several inches of snow.

My personal view is that the guard on Merseyside who has been convicted of manslaughter has been treated very unfairly. I agree. A lot of people on here were extremely hard on him but, as I pointed out, I have many times seen trains move off with people in much more dangerous situations (e.g. people kissing goodbye through the window of slam door stock). It was one of those occasions where something terrible happens as an unlikely result of something that is going on all the time and suddenly the poor sod who's on duty is treated as if what he did is somehow infinitely more egregious than all the other instances of similar actions that did not lead to a tragedy. Seems to be the season for such things as in platform/train interface incidents - Waikanae Station yesterday morning. ps. I hope you're using the modern definition of 'egregious' = very bad, rather than the not-so-old version where 'egregious' = very good.

Therefore of the old mechanical cabin, which closed in September 1905. Looks like there was some layout rationalisation when the EP frame came in as the EP layout had trailing crossovers either end of the platform.

Doesn't match up with a 1907 diagram I have of Putney Bridge. <shrug> puzzling.

I think the cabin is the wrong side of the line for Putney Bridge with the EP semaphores *unless* it is after July 1910.
I suggest Hammersmith but the geography is wrong, and it doesn't seem to fit what diagrams I have from the MT6 files for the Acton Lane Junction - Galena Road widening - insofar as the existing plans are shewn. Doesn't fit Parsons Green either.
Curious.

ISTR that there is a much more esoteric explanation, as the original pilot lights were not blue.

I'm having a quick dig through... I know I've got something, somewhere.
Ealing Broadway controlled Hanger Lane IMR from 1/11/59; Box WO at Hanger Lane opened 23/6/03, signals became semis in July 1905, closed 9/5/25 with control passing to Ealing Common the day after.
I might have a diagram of the 1925 - 1959 arrangements, as well as the diagram of the 1907 arrangements and the locking: send me a PM via 'the other place' (JH).

The presence of Southend excludes anywhere before North Ealing the South Harrow branch, <gentle voice> No, it doesn't. </gv> I cannot find all my RSTD notes to check something, but I have dug through the WTT notes - the District had the running powers for three trains an hour beyond South Harrow to Uxbridge and also ran three trains an hour to South Harrow. This stopped on 4/7/32 (I have the WTT for this Picc extension in my hands); I also have all the signalling notices. Doing a joining up exercise, the TD for 'Southend' would be common along all branches of the District EB; granted there may be portions of line where the same code could be used for a different train, but more likely that the code was 'reserved': this is still the case with some District TDs today, where BDE (say) is prohibited Rayners Lane - Ealing Broadway, Earls Court - Mansion House, East Putney - Earls Court but is used High St. Ken. [ex Olympia] (West Kensington - Earls Court). It is a long, long time since I looked through the WTTs plans, so I cannot say exhaustively that Southend trains were ever considered to run from Uxbridge pre-July 1932, but what I can say is given this selection of destinations it is for a one-way unit that would be at the westernmost end of the RSTD system, most likely before the four tracking was completed. I have now carefully gone through the operating paperwork of the time, and if all the photographs are contemporaneous I say that this unit was at South Harrow and was spare at the times the photographs were taken. It is a 'universal terminator' (actually, a 'universal transmitter').

Another couple of photos from "Everyday Knowledge in Pictures" an undated book but a fascinating read. Not sure where this is, looking at the destinations available How about West Ken West? Not going both ways, surely? Or did it make the switching-out easier? <Hmm>
