thank you very much for this. A question - why do we see some white route lights flash on briefly then off? (e.g. near 1:34) Or is this something to do with route cancelling, but the red lights do not show up so well in the film? Log in to reply |

" said:It looks like the track circuits in question were occupied, and as they cleared the white route lights remain briefly before clearing. If you watch closely (and run at real time or slower), you can see it happening on SimSig.

" said:" said:It looks like the track circuits in question were occupied, and as they cleared the white route lights remain briefly before clearing. If you watch closely (and run at real time or slower), you can see it happening on SimSig. That is what happens. I've seen it on every panel I've visited. The approach locking holds the route until cleared down, section by section, and every section of route that's held is indicated by the white route lights. As each section (usually an individual track circuit) clears, the approach locking relays take a moment to respond (there's quite a few relays in the system and, being cascaded, each one depends on the preceding one having operated). Some panels are quicker than others (and of course it depends on the entrance button having been pulled up in any case, unless it's a TORR panel).
