Signalling afficionados will remember the Ealing and Shepherds Bush Railway as being one of the very few installations in the country with three-position automatic signalling.
I've been very fortunate and managed to acquire a scale coloured signalling plan of the whole railway - I'm not sure of the date, but I suspect that it dates from 1917 - 1920. The black work is printed, but the diagram is hand-coloured and contains several pencil alterations to Wood Lane Junction at the (then) end of the Central London. It seems to include a suggestion for a very simple White City. West Acton is still in the future, and not on the plan, so it certainly dates from before 1923; East Acton is shewn as 'Erconwald Street Halt'.
Some further research is needed on why and when certain signals were taken out of use, but as a little taster of the original (if anyone is interested, that is ;D) here are the plans for
Signalbox 'J' Wood Lane Junction
Open from 1920 to 1938. You can see at the bottom of the diagram the overbridge just before White City where the 'wrong - way' running after the 'Caxton Curve' sorted itself out.
Signalbox 'K' North Acton
Years before the extension to Greenford and the grade-separated junction, this is what North Acton Junction looked like, controlling both three-position signalling on the E&SB and 'ordinary' semaphores on the main line.
Signalbox 'L' Ealing Broadway
This signalbox worked with both the District and the GWR <spit>, note that although the signals were capable of showing the horizontal (stop), 45 degrees (caution) and 90 degrees (clear), only the 45 degree aspect were used on the approaches to Ealing - even on the Outer Homes - this was a more cautious signalled approach to a terminus than existed for many years on the UndergrounD until the tragic events of Moorgate in 1975.
Enjoy - I might web up the coloured parts of the plan if there is interest; when I've finished editing the photographs. ;D
