What does a double yellow signal mean please?

[Fast]

I know what a yellow signal means on its own but whats a double mean?

[FusedCircuit]

Pretty much the same just over two tracks instead ! :) (I think)

Double yellow means the next signal is broken and you can proceed past it at full speed.

are you sure?

In the UK anyway, a double yellow signal means that the next one is a single yellow. Broken signals are red, and you need permission from the signaller to pass (TAB in TS).

Low stand signal means approach slow

A red signal doesn't mean it is broken it means there is a train present in the next signal block.

Basically

Green signal means the next signal block is clear for at least two signals
Double yellow means that the next signal is yellow and you should be slowing down
Single yellow means the next signal is red.
Red signal means you must stop, because there is a train in between the signal or the route has been set for another train.

You should not press tab at all Red signals that is not the point of using the tab function, the tab function should only be used if you need to move into an occupied block either for shunting moves or for coupling to another service.

If the signal is Red it is most likely for a reason; pressing tab will, in a lot of cases, cause a potential crash with an AI or a derailment with a junction set against you.

Nope! Not always the case. A single yellow means 'Caution', the next signal 'MAY' be a Red. I've had single yellow lights only for the next one to either still be yellow or even green.

Fair point, I stand corrected :) Although in most cases on a main line it will most likely be a red when you pass the yellow however by the time you get to the next one the section ahead of it might have cleared :) and might have change from red to another yellow, two yellows or a green.

(unless its an approach to yellow junction of course)

PS - Generally a single yellow does mean the next signal is either a red or a junction, however by the time you get to that signal it might have changed since. (so is red when your train is at the yellow signal )

The right answer is sohome. At least in most of railroads in USA.
Two yellows lights in a signal means: There is the main and a diverging track. Both tracks have a train or consist two blocks ahead of yours, so get ready to stop in the next signal, as you could get a red light. There may be also a switch set against your track (i suppose that is what is called here a broken...), two blocks ahead.

Here in Australia it indicates you will be diverting at the next junction. (Medium Turnout).
Maybe one day we will see them in TS......

You mean Australia or the double yellow? The latest has been in TS for a long time. Check the Sherman Hill manual for the signals part.

[Sharpey™]

Australia and its signalling system... I was alluding to the fact we havent had any Australian content for TS in 7 years....

Single yellow means the next signal is red. Double yellow means the red light is twice as bright and the driver should put on sunglasses.

You're all being far too helpful to someone whose copy of TS and *all* its DLC (his claim) has apparently fallen off the back of a lorry.
