Hi,

In the attached save...

Train 2E68 came to a stand at E35 which wouldn't clear. Signaller cleared the route into P6 as shunt E35-E677 & E677-E137. E35 showed call-on and E677 went white.

However, 2E68 then complaining because E677 unlit. After train was talked through the G/S it changed back to a red display as the route released. Is this a display/behaviour bug?

Thanks
Jamie

From the wiki:

Quote:
Shunt signal aspects are not necessarily 'proved' lit, and so a failure will not necessarily be shown on the panel.

Someone who knows the control tables would need to confirm, but I wonder if E677 unlit (it is a facing shunt in several routes from E35) would hold E35 at danger for one of those routes even though the fault wasn't indicated on the panel?

I noticed the E677 bit myself when I took over Panel B and I did wonder if it was a bug. I expected that the signal would not go white if it was unlit. I wonder how it would show on a real ROC layout.

Well...

It would depend if it was lamp proved or not.

In WR E10k interlocking, present shunts normally only require the shunt to be "Not On" in order for the main signal to clear.

As long as the shunt is called to an off aspect, the main will clear, even if the shunt isn't lit.
