ColHut Posted April 4, 2014 Share Posted April 4, 2014 G'day wise ones. I was looking a little more closely at the LNER signalling requirements for moves from a siding to a running line. Assuming the siding had a head shunt (or similar line to other sidings etc), it would seem that a single small yellow semaphore arm could control access to the running line (with appropriate interlocking of points and signals), and be passed without being lowered for movement to the head shunt or other siding. At least such things seem to be referred to in the regulations. My question, is what do single small yellow semaphore arms look like in terms of markings etc? Or am I confused and the reference is really to discs with yellow bands or standard small semaphore stop signals Regs below. 1931 version: GROUND SIGNALS (DISC OR DWARF), SEMAPHORE SIGNALS WITH SMALL ARMS, AND SMALL COLOUR LIGHT SIGNALS, USED IN PLACE OF DISC OR DWARF SIGNALS. 47. Disc or dwarf signals, semaphore signals with small arms, and small colour light signals, are used to regulate the passage of trains from a siding to a running line, from a running line to a siding, between one running line and another, and to control shunting operations. In cases where these signals have a yellow disc or arm or exhibit a yellow light they may be passed, without being lowered, for movements in a direction for which the signal when lowered does not apply. 1937 version - Draw-ahead and Shunting Signals:- 47. Draw-ahead signals, where provided, are placed below stop Signals not controlling the entrance to the section ahead. Shunting signals are used to regulate the passage of trains from a siding to a running line. from a running line to a siding, between one running line and another. and to control shunting operations. Draw-ahead and shunting signals apply when lowered as far as the line is clear towards the next signal only, but the lowering or turning off of such signals does not authorise the next signal to be passed at Danger. Shunting signals of the types described below may be passed. without being turned off or lowered. for movements in a direction for which the 'signal when turned off or lowered does not apply:- Signal having a yellow arm or disc. " “ “yellow arm on a white disc. " " "yellow light. Position light signal having yellow and white lights. Link to post Share on other sites More sharing options...
micknich2003 Posted April 4, 2014 Share Posted April 4, 2014 Minature Yellow arms are identical to the red version, except they are coloured yellow in lue of red. Link to post Share on other sites More sharing options...
ColHut Posted April 5, 2014 Author Share Posted April 5, 2014 Thanks Mick. I finally found a real pic on the Southern E Group website: http://www.semgonline.com/proto/semaphore_10.html and on the preceding page. regards Link to post Share on other sites More sharing options...
bécasse Posted April 5, 2014 Share Posted April 5, 2014 But that is the Southern take on the issue, not the LNER's.......... a bit like saying Aussies and Kiwis are much the same thing! The LNER's yellow discs were just like the red ones except for the colour of the stripe (which I suspect was topped and bottomed by black lining as was the LMSR equivalent), but I don't remember ever having seen an LNER yellow arm although they must have existed as the LNER was probably keener on using miniature arms (rather than discs) at the exits from sidings and loops than any of the other big four.

I have been doing a lot of research on behalf of the new 7mm project and I will shortly be burning a few disks. Link to post Share on other sites More sharing options...

ColHut Posted April 5, 2014 Author Share Posted April 5, 2014 But that is the Southern take on the issue, not the LNER's.......... Agreed, cannot seem to find a picture in colour of the real deal.

ColHut Posted April 5, 2014 Author Share Posted April 5, 2014 Thanks Mick! Some look like they are wire operated, some by rods, or is the rodding on 'LNER Ground disc1' just part of a locking or interlocking mechanism? The white 'diamonds' are to indicate track circuiting? regards Link to post Share on other sites More sharing options...
micknich2003 Posted April 5, 2014 Share Posted April 5, 2014 Col, they are all wire worked, the rods you can see are the mechanical Detector slides. Yes, the White Diamonds indicate a TC, and exemption to Rule 55 etc. Link to post Share on other sites More sharing options...

kenw Posted September 2, 2014 Share Posted September 2, 2014 Don't think I've a pic, but there was a yellow miniature arm at Wearmouth Jnc from the Yard to Down Main, with a short headshunt straight ahead. It was mounted on the main post of the bracket carrying the adjacent Down Main signal. The Southern one shown on web site referenced above is unusually large, they were normally the same size as normal miniature arm shunt signals, just yellow / black band instead of red / white, and yellow lens instead of red. Generally, as already stated, LNER yellow disc signals were yellow band on white disc, but Hall Dene did have a yellow on black one. Also on the Southern web site referenced, when giving descriptions of signals, unfortunate use of regional slang, they were never 'dummys' in the NE Link to post Share on other sites More sharing options...
RMweb Premium Loxborough Posted September 21, 2014 RMweb Premium Share Posted September 21, 2014 Resurrecting this interesting and informative topic with (if I may) a supplementary question about which I have been wondering for some time... My understanding of shunting signals is that they indicate that they indicate that points are set for a given route and that a train may move along that route as long as it is clear, but thay they do not necessarily indicate that the track is clear. ie driver is to proceed with caution, be ready to stop etc. All well and good when setting back into a siding or puffing too and fro in a shunting yard. How does this work, though, where a disc indicates a route onto a main line; does the driver set off at a slow speed, half expecting to come across another train, or is there some special arrangement whereby a shunting signal onto a main line indicates that the line is clear? Or have I got it totally wrong? Thanks all, G Link to post Share on other sites More sharing options...
