Parsonage Road - LC Failure update? 22/09/2024 at 13:32 #158616

Online 		Just curious as on the 14th May 2022, it was faulted on Mantis as 36122 but if you click on Documentation than Mantis Issue Tracking which is open to everyone, there is no mention of it.

Any idea if this issue has been resolved or not as in the May 2022 timetable, so far every train that calls at Littlehaven in the UP direction seems to generate a crossing failure for Parsonage Road.

I've not included a save because it was first reported in 2015 and the last update was from one of the SimSig team who reported it on Mantis.

Hopefully Geoff can bring this to the developer's attention too please?

You may be describing a different issue, which happens now and again when there are AHB in long track circuits with stations or slow trains.
The crossing goes to 'fail' if the TC remains occupied for too long, as a precaution against trains running back. The real thing may have some changes that are not apparent in the sim or when designing the sim.

The 2022 timetable has 4 minutes Horsham Dep - Littlehaven Dep, and generates the fail as you state, while the 2009 has 3 minutes and does not fail the AHB due to different standing times at Littlehaven.

testers - see discussion under #24433.

That's wrong than as I've managed to recreate it numerous times with different consists departing from Horsham towards Three Bridges using both Class 377 x 2 and a Class 700/0.

Every time, when trains stop on the Up at Littlehaven it always says that the level crossing in question has failed so it's impossible to show it as unable to reproduce when it's easily recreated every time.

In the saves below, you can see that 1C90 arrives at Littlehaven at 06:52:32 and I get a level crossing failure notification at 06:53:34 and that's just one example, note that the Thameslink following it arrives at Littlehaven on time and without fail brings up the crossing failure so there is a issue there.

Can this bug report be reopened on Mantis as it's hasn't been fixed.

I can't comment on the Pre 2012 layout but this bug certainly happens on the Post 2012 layout, frustrating that it happens to every train that calls at Littlehaven in the Up direction.

You say it is easily recreated every time, yet both the original person who determined it could not be reproduced and Bill today were unable to reproduce the issue as logged on Mantis. It should be noted that what is logged on Mantis and what you have described today are markedly different issues, so far from being "impossible" it is understandable why it was not reproducable.

I believe I can see why it is happening though, so have logged a fresh ticket Mantis 41397

That will shorten the TC occupation after passing the crossing and you won't get the alarm.
(tested 2012+ era, by edit of 1C03 from 2022 timetable)
