One for the Developers but if you've already got the signalling diagrams for your sim, is it difficult to then add a banner repeater to a specific signal or even remove a banner repeater?

Banners are a strange one though, just because it's there on the ground it doesn't always mean that it's even drawn on the panel. And even if it is drawn on the panel it doesn't mean it actually indicates on the panel.

As Headshot says. Generally though, with CBIs banner repeaters are usually shown on the screens and whether they're lit or not. Not always. Some even show dual banner repeaters with each proved lit separately.

I'm always amused by the way that banner repeaters go back to a "danger" indicator once a train has passed them, but before passing the signal that they repeat. Strictly speaking, it's momentarily showing the "wrong" aspect".

I personally would say that is a safe and correct method of working, Lets imagine a nice thickly lined track on a 60 degree curve and a train fails between with four coaches past the signal (the replacement block joint for which is 6 coaches past the signal) which is 15 coaches in advance of the banner. Now ignoring the rules side of recovery of a failed train, which is safer by giving more of a reminder to the driver of the assistance. A banner indicating that the signal is showing the line is unoccupied (which the track that returns the signal to danger actually is) or a banner showing that there is danger ahead. In the words of a certain recently deceased Liverpool female entertainer the choice is yours...... Paul You have to get a red before you can get any other colour Log in to reply |

" said:I'm always amused by the way that banner repeaters go back to a "danger" indicator once a train has passed them, but before passing the signal that they repeat. Strictly speaking, it's momentarily showing the "wrong" aspect".An incident occurred in Ipswich (QLD, Australia) involving a Repeat Signal that was not designed to restore after passage (and a running shunt). If you refer to the diagram below.... (Please excuse the crudity of this model. I didn't have time to build it to scale or paint it :lol: )  Train 2 (passenger EMU) arrived from Brisbane and terminated on (curved) platform 4. As it was waiting table to return to Brisbane, a light engine (Train 1) was signalled out of the yard behind IH5. IH15, by this time, had been cleared for Train 2 to depart, thus resulting in Repeat Signal IH15P showing a clear aspect. The Signaller then cleared shunt signal IH5 to IH15 (I can't recall why he didn't send it via P2 or P3). Train 2 moved off then saw IH15P showing clear so started accelerating. Fortunately it stopped before running up the bum of Train 2. As a result of that incident, IH5 was converted into QR's first absolute shunt signal (the Signaller got a hefty kick in the arse too). EDIT NSW colour light Repeat Signals have a Red aspect to prevent just such an incident occurring. Post has attachments. Log in to view them. Not fat ..... fluffy!!

Perhaps QR should look into Huddersfield controls!

" said:Perhaps QR should look into Huddersfield controls!I thought that, but is it generally applied to routes from shunt signals? A quick test on SimSig suggests not.

One point worth noting - until that incident occurred, all QR shunt signals would clear onto an occupied track unless it is a running shunt (called a "Leading Shunt" in QR) which has been cleared as part of a running route. This is why I used to get confused with Simsig when certain shunt signals would not clear onto an occupied track (and designed that way).
