The overlap of S110 is drawn as ending on track circuit TVF, however it actually needs TVE to be clear too for the signal to show an unrestricted aspect.

The actual IECC shows it to include circuit TVE: https://photos.signalling.org/picture?/20580/category/2198-2014_may

Personally, I don't see any difference between the VDU and the sim. The junction is protected with double red protection on both inbound lines and signals are stepping up as expected after the passage of trains and ones following behind. The sim already represents what you have mentioned. 110 won't show a proceed aspect until the route is set and clear to 100 signal. Signal 120 won't show a Y until the TC occupation timer kicks in OR 110 is showing a proceed aspect. How to report an issue: www.SimSig.co.uk/Wiki/Show?page=usertrack:reportanissue Log in to reply |

I'd agree with Dionysusnu here. Overlap marker drawn incorrectly on VF instead of VE in sim. Full overlap of S110 includes VE track. S120 shows red with S110 route set and VE occupied.

Instead, it requires the route from 110, and track circuits VF and VE to be clear. At 110, there are two lines drawn to show the overlap modes of 120 (delayed and free aspects). The first line is correct, but the second line is placed at the end of VF. This is wrong, because VE also needs to be clear for the full overlap. Looking at the attached image from the real IECC, it is clear that the SimSig drawing is different. Last edited: 23/01/2022 at 20:53 by Dionysusnu Reason: None given Log in to reply |
