Where have you seen??

[q8]

I have a mate who worked for LUL and like me is now retired who was having a bit crack with me on the phone today. He is not a member of this forum but does look now and again.

Now he said to me that there is (or was) somewhere on the LUL combine where a shunt repeater signal is installed. I cannot for the life of me remember that but do you lot know?

(A shunt repeater apparently looks the same as a normal shunt but the band across it is yellow outlined in black. I said he meant a disk distant but he says no. A shunt repeater has a white background to the yellow band.)

Hmmmmm. www.signalbox.org/signals/semaphore4.htm says that a yellow shunt disc is the same as a red shunt disc, except for one thing - it can be passed at danger if the shunting movement is only along the headshunt. Is that what your friend is referring to?

Wood Green siding according to the Traffic Controller's diagrams.

I dunno to be sure TOK I 've never seen one. But he did say the broad band was yellow on white.

Fascinating!

What's so special about Wood Green that it would need a shunt repeater? And why is it then that Down Street doesn't have any?

[Tom]

My theory is that the repeater is positioned so that a 3 car Aldwych Shuttle train could fully berth up to the 6 car stop mark and still be able to see the aspect of the outlet shunt signal. I prepare to be corrected though...

Sounds right enough to me Tom

Ahhhh - you never did say where the shunt repeater was

In that case it makes perfect sense that it would be placed in such a location.

Still though, my second question stands - why does Down Street lack a shunt repeater? Is approach control used instead? Surely there has been a time when a motorman (or T/Op) has forgotten that he is doing a shunt via the siding and almost hits the facing points at line speed, right?

[q8]

I think you'll find that Down Street comes under different criterior TOK. In that it is an emergency only reversing siding somewhat similar to Holborn. Whereas Wood Green etc, are in more or less regular use.

I don't think are applies any more, it is more of an emergency siding these days.

There used to be a shunt repeater at Rickmansworth RJP13. It can be seen on the diagrams that I put on the net last week that can be seen here (422KB)

In this case I assume it was provided because of the platform curvature.

and also as an aid in the days of engine changeover at Ricky.

just going thru some old posts and thought i'd offer some info:

There is (as most of you know) 2 banner/disk-type repeaters approaching ricky on the up road, one is for JP1 and the other for the up starter (can't remember number off top of my head). These IIRC have a black band (as per main line) but a yellow background and were installed either when the area was resignalled 1953 or 1960-62. Again, i can't remember exactly.

More interestingly, there were also some disc shunt signals with the yellow band at Ongar, prefixed LZ but i can't recall if they were LNER installed or of the LT type (probably the former). They were removed when the yard closed around 1969.

Hope this helps

D'oh! Just seen the previous two posts regarding the signals at ricky! Obviously the one i couldn't remember was RJP13. I am fairly sure both are still in use. (its been a while since i bombed down the gradient from chorleywood with the needle off the clock!).

Not anymore. They are now white discs with black bars; the discs are about 25% larger than standard shunt signal discs.

A quick bit of research shows that full back bar discs are used to repeat MAS stop signals, so the discs in use follow standard NR practice.

These are our local (very rare) repeaters:

Exit from Marchwood MOD to "main line" at Marchwood, because of the bend obstructing the view of the normal shunt and

Eastleigh East Yard ...but note that it is illuminated whereas MW10R has lights behind.

This is the shunt at Marchwood that the unique repeater MW10R is for:

What i meant to say was that the background was/is cream, not white, but can appear yellow. Perhaps discoloured over time. As you say, they are essentially a copy of BR banners. These WERE installed in 1953. The second is not RJP13 as i stated but RJP2, repeating the up starter which is out of view, i presume for the non-stopping expresses of the day. I have now consulted my linebook which shows RJP13 shunt-disc repeater halfway down the platform on the down line (up direction) for locos leaving the sidings north of the station to run round. By 1962 the sidings had gone but the disc was still there. This disc was the same size as a shunt disc but with a yellow band.

Other locations for these discs included Croxley yard, South Woodford yard, Snaresbrook Yard and others on the Central.
