Track circuit failure in non-circuited track! 23/05/2020 at 19:30 #127051

I had a clearing point violation at Auchterarder 5 with all points set normal and no track occupied as far as Perth.

After some minutes of investigation, I found that a track circuit fault had been reported at Auchterarder, and in the Incident Control Panel, I found that AR3947 was occupied.

AR3947 seems to be the berth track circuit for AR6, but it's drawn as non-circuited track.

This is most unfair!

Can we have a check in the code which prevents faults in invisible track circuits ?

It's not that simple, I'm afraid. Something drawn as non-track-circuited is just a bit of decoration as far as the code is concerned, no different than platforms or station names. There are occasions where real TCs aren't drawn, so it's hard for code to distinguish the situation.

It is possible for the developer to explicitly set those tracks as unable to fail though, which they have appeared to have done for almost every other bit of non-track-circuited track.

I've raised a mantis ticket (30599) for the data issue that caused the original report.

I do concur that the code wouldn't be able to tell the difference itself

Other way round: you have to set the track as able to fail.

That was my point: there's no way to make a separate check (e.g. does the track circuit get drawn) that it should or shouldn't be able to fail.

To expand on that a bit: off-sim areas such as fringes are usually drawn to aid during development and testing, so "is it drawn" won't work. They're just not within the visible screen area in a release version.
