Just a thought for the future. could failed route indicators be simulated where only one route of a main aspect with multiple routes fails to clear, remaining at red where the indicator has failed to prove, but clears correctly for all other routes. I suspect not as simple to recreate with specifically coding which route doesn't use an indicator at all but still an idea.

A good idea, I would like to see this if it’s possible?

SimSig doesn't know whether routes have stencils or feathers given current sim data. However, such routes are often also approach controlled. Maybe routes with approach control being able to fail would be a good proxy for routes that have route indications liable to fail?

I recall raising this as a feature request on mantis a very very long time ago - not in a position to root around at present if someone wants to dig out the ticket number...

Im not sure feathers/stencils/theatres are proved? I’ve seen the 14 indication at Piccadilly fail and the signal cleared at normal - the signaller was only aware when the first train stopped to query it.

Feathers are unlikely to fail with them consisting of 5 lamps, the first a signaller would know is if a driver was to query the route or an RT3185 form is filled out to inform Network Rail of lamps being unlit.

There's the right way, the wrong way and the railway.

Unless things have changed 3 out of 5 need to prove for the signal to clear

That was my understanding too. And where the old multi-lamp theatre indicators were provided, proving had to ensure a mutilated indication couldn't be misread as a different indication. (Imagine trying to work that one out!!!)

Depending on the indications, it isn't too hard. The example in the text books is "P" versus "F", where you just prove most of the lamps in the curved bit of the "P".

Also, you only need to prove if misreading would produce a serious risk or operational problem, so where there's a noticeable difference in speed or if the feathered route leads you off the end of the wires.

As others have pointed out, it's not as simple as "lit" or "unlit". Theatre boxes are the worst (the ones made from forming letters/digits out of dots of light rather than stencils) can be proved for some characters and not others. Some routes have two indicators (SN120, unless it changed with the recontrol).

By "SN" do you mean Swindon?

I'd guess Geoff is referring to Slough New in this case.

Yes, sorry. Setting the route up line 3 from there used to take ages because first one indicator had to be proved lit before the 2nd, until finally the signal aspect could show proceed.

In that case, SN120 now has THREE junction indicators (1, 2, 3), with four routes available. Although indicators 2 and 3 are in use, I've never seen them lit. They'd only be used for trains being sent from the Up Main across to Lines 4, 5 and 6 (which becomes the new Crossrail East line at Westbourne Park Junction).
