In the attached screenshot, the first train to reach the TC Failure will be on the Down line. As far as I can see, the nearest signal which I can control is at Carton Loops, somewhat in advance of the failure.
Have I got to stop a train there and ask the driver to examine the line and subsequently at each signal before he gets to the failure? And would this be the case in reality?

In reality, you could stop him at Carlton and advise him to examine the line from single X to signal Y and report back at signal Y, and he would travel down to signal X and then begin an exam.

Theres no option at present in Simsig to do this so I spose technically you'd have to get him to examine to each signal and report back. I don't bother in cases like this and just run the train normally (my excuse is I'm lazy and its not the real thing, in which case I'd do it properly)

Isn't this the same situation as https://www.SimSig.co.uk/Forum/ThreadView/54169 or https://www.SimSig.co.uk/Forum/ThreadView/53257 ?

Oh dear. I keep asking the same question and I think that this is the third time :/

Please accept my apologies. It's down to a poor memory. I promise not to aske it again, unless that I forget. Only joking :O

In reality, a train on the down line cannot examine the up line for a track circuit showing occupied when clear. Rule book TS1 Reg 20...

20.6.2 First train to pass on an adjacent line

If the first train to pass on a line immediately next to the affected line before the affected line is examined, the driver of this train must be told:
• what is happening
• the locations between which the adjacent line is affected by the track circuit
• to pass the affected portion of line at caution
• to report as soon as possible if anything is wrong.

So if nothing is seen to be wrong the driver does not have to report back.

This facility is not currently available in Simsig.

Have never been able to find any mentions of the following in the Rule book so for failures on adjacent lines, how ready should the signaller be to throw a signal (eg. controlled vs. emergency vs. replacement) back in an approaching drivers face?

How does current practice with GSMR compare with yesteryears?... Stories most welcome...

In Zone 6, no one can hear you scream...

On a related note, would "immediately next to" also include the line if there is a "ten foot" for signal posts?

Thanks

Interesting that, as you say, there is no specific mention in the rule book.

What it does say though is:
(Part of) TS1 Reg 20.6.1 Before the passage of the first train
....Unless you are sure that the line is not obstructed, you must arrange for the line to be examined...
and
20.6.4 When it is known the affected line is not obstructed
If it has been confirmed that the line is not obstructed, you must treat the track circuit as having failed.

The latter would indicate that until the line is confirmed as not being obstructed, you should treat it as an obstruction of the line and therefore apply...

TS2 Regulation 4

4.1 Stopping trains because of an emergency


4.1.1 Signal protection
If you need to stop trains because of an obstruction or other emergency, you must place or keep at danger all signals necessary to protect the affected line.
If necessary, you must arrange for train radio messages to be sent.
If you cannot stop a train proceeding towards the obstruction or other emergency, you must carry out the instructions shown in regulation 5. (train or vehicles proceeding without authority)

So on that basis yes you would put back in front of an approaching train or make an urgent GSM-r call.
