What does this sign mean?

I saw while I was at Rutherglen today, the sign had two lights flashing in the black arrows towards Polmadie, I also noticed some bright yellow signs further round the track but I could not read them.

What I saw (train wise) while I was there

It is an emergency indicator - it provides advance warning of an emergency speed restriction. Incidentally that is the reduced clearance version. The standard version has 3 chevrons..

 

[Sir_Clagalot]

It's called a dalek, indicates to drivers that they are entering an engineering possession area. (if it has red lights in means you are leaving it). There *may* be an associated speed restriction with it but they are yellow reflective boards with the speed on it, no flashing lights at all.

Not quite, it's a warning board for an emergancy speed restriction. The sign in the picture dosnt have anything to do with engineering possessions.

The engineering possession boards are slightly different, they do have red or yellow lights depending if you are entering or leaving but they are also a different shape to what the op has in this picture

This is an emergancy speed warning and further down the track there will be a speed warning indicator and then the speed board.

You don't get a speed restriction sign with engineering possessions as the speeds are fixed in the rule book. A pre-planned temporary speed restriction would not have one of these signs the op has given a picture to. It would just have a speed warning a speed indicator.

Also known as Metal Mickys.

But these are informal rather trhan official terms..................

The limit of possession boards have a STOP sign with a flashing red light over it attached to the rail. Worksite marker boards are the ones you are referring to, vertical yellow plastic boards that attach to the rail with 2 red lights on one side and 2 yellow on the other. These mark the entry to/exit from an engineering supervisor's worksite within a possession.

It is for an emergency speed restriction (a restriction imposed at very short notice), not an advertised temporary speed restriction.

But these are informal rather trhan official terms..................

Of course the official name is an EROS board, or in the case of the one pictured, a Mini EROS. They are not to advise of "entry to an emergency possession" as described above, but rather to advise of an emergency restriction to line speed.

Sir Clagalot is referring to a Marker Board (Link) which has both flashing red and amber lights - one to denote entry into a PICOPS area and one to denote entry to an ES area.

Of course the official name is an EROS board

No, the official name is an "Emergency Indicator".

Yellow, not amber.

When and when are these signs not used? Sometimes the first indication of a Temporary Speed Restriction you get is a board showing the speed with lights.

Incorrect!!!!!!

The first indication you get for a TSR is posted in the W.O.N.
The next indication you get for a TSR is the magnet. 183 Metres down the line you get the TSR advanced warning board. After the required braking distance (dependent on line speed) you get the commencement board.

Also, on the routes I drive over, the white lights have been replaced by retro reflective white discs.

Definately a Dalek!
