Doughnut Posted May 9, 2014 Share Posted May 9, 2014 I know that generally, in this country, the signal should be on the left of the line, but I have seen signals positioned to the right. What are the rules on this? I only ask, as I've just noticed that I've plonked my latest signal to the right of the line, by mistake, but it would be a real pain to move it and it would be quite tight clearance-wise, if it were on the left. (Colour light- modern image) Many thanks Dave Link to post Share on other sites More sharing options...
rovex Posted May 9, 2014 Share Posted May 9, 2014 Stationmaster can probably give you chapter and verse, but I expect the rule is on the left, unless siting and or viewing conditions dictate it has to be on the right Link to post Share on other sites More sharing options...
Merfyn Jones Posted May 9, 2014 Share Posted May 9, 2014 Generalisation. Signals usually on the left except on the GWR/WR. Lots of cases of otherwise for sighting purposes, tight curves etc. As usual a photo of the prototype always helps. Merf Link to post Share on other sites More sharing options...
RMweb Gold TheSignalEngineer Posted May 9, 2014 RMweb Gold Share Posted May 9, 2014 Modern image colour light signals are generally to the left of the line. See clause C1.2.1 for the instruction and C1.2.2 for the get-outs. http://www.rgsonline.co.uk/Railway_Group_Standards/Control%20Command%20and%20Signalling/Railway%20Group%20Standards/GERT8037%20Iss%201.pdf Link to post Share on other sites More sharing options...

There's a ground mounted 3-aspect at Blackburn - on the tamper siding. I can't see any particular reason as to why it's there - even when checking with the associated Clause 1.3.4 on "read-through" It's just visible in the distance to the right of the up/down goods loop starter. We've recreated the signal on Blackmill, complete with red aspect at the top. Cheers, Mick Link to post Share on other sites More sharing options...

Cheers, Mick Hello Mick I'm trying to place what the layout is now, that bracket was for what were the Up&Dn Through and Platform 2 when the interlocking was commissioned.To the left used to be the Parcels platform then the Up & Dn goods. IIRC the Parcels Platform had a LH offset signal to the right of the line just ahead of that bracket. Is what is now the Tamper Siding the old Parcels Platform road? If so the signal must have been altered at some time and positioned to give more standage. It was probably retained as a main signal as it would mean less work than changing it, and the fashion for signals at sidings exits has changed several times over the years depending on area.

Eric Hi Eric, The parcels platform is long gone - probably the tamper siding as you now say - it is in line with the original platform before the station was rebuilt. I have a (mid-2000's) copy of the diagram somewhere, I'll try to locate it. Cheers, Mick Link to post Share on other sites More sharing options...
Edwin_m Posted May 9, 2014 Share Posted May 9, 2014 Ground signals are sometimes used where a signal is needed on a line adjacent to a main line, but there is no signal on the main line at that location. I guess the idea is that the signal is low enough down and far enough away to avoid confusing the driver of a train on the main line. There used to be one like that between Beeston and Nottingham before last summer's re-signalling. Link to post Share on other sites More sharing options...
