From my rather old experience of SSI data I'm pretty sure OFF indicators aren't proved in any way, so the signal can clear even if the OFF has failed. However this doesn't explain why drivers can't take notice of them, as if they are driven by the same vital circuits it's not credible for the OFF to be lit if the signal is at danger.
I don’t think it’s the case that drivers can’t take notice of them - other than the risk that an ‘off’ indicator applies to the signal behind the train, I don’t see a problem. There are one or two that I find useful. I’d understood that it was just the case that they wouldn’t be provided for that purpose.

Just a footnote to this project:
Leaving platform 6 at Lime St today (the one that goes though an arch at the country end), I noticed it had no fewer than THREE banner repeater signals before the starting signal near the arch.
Is this some kind of record in the UK? I can't think of a similar case elsewhere...
I didn't reply earlier without confirming this morning, but each of the 4 platforms at Portsmouth Harbour has 3 banner repeaters. I suspect they coincide with sighting positions from various train lengths, eg, 4, 8 or 12 car. Also seem to be combined with CD/RA indicators.

I've never looked but has Lime Street got TPWS ramps now? 10 MPH into the platform?
It had overspeed loops approaching the buffer stops before it was remodelled too. The set speed for the TPWS (50m or so from the stops?) is around 10mph, and permissible speed into the platforms is 15mph but some TOCs’ policies require a lower speed.

Nice, thanks for the info. :)

Not sure if this is the best thread for this question but does anyone know how the signalling work over Xmas in the Liverpool area went?

No trains between Runcorn and lime street all over the holiday period.

Trains seem to be running OK today, on the normal routes.
Presumably the signalling at Allerton/Speke/Garston is now controlled from Manchester ROC.
I see from the web site that Ditton and Halewood are next, in May (or next December according to the NR web site).
I'm still a bit confused about Edge Hill.
I thought I read somewhere that it was a later transfer to the ROC, but RTT shows a timing point called "Former Edge Hill SB".
Does anybody know if it is still controlling the routes to/from Lime St?

Have they actually finished all of the refurb work at Lime Street station?

The floor of the new platforms 6 to 10 are all nice and new, but you get to the main concourse part of the station and they've done nothing with the floor and there's uneven bits.

Also, at the end of platforms 7 and 8 they have put TV screens showing departures/arrivals right in the middle of the platform exit, meaning that when it's busy there is a bottle neck and passengers who are trying to get onto and off the platforms have to get past crowds of people who are looking at the departure screens!

And the entrance onto Skelhorne Street is still a bottle neck with just the one set of sliding doors, made even worse when it's busy and people are queuing for taxis and the queue backs up onto the concourse, blocking people trying to exit/enter the station.

And there's still no ATM's on the concourse. Nearest one is still the one over the road next to the Sainsbury Local.

ATMs were moved from the old Platform 7/8 area prior to their redevelopment and installed on the main concourse outside W H Smith.

I was told about a month ago that they would be in the new "shed" being fitted out down the alcove to the left of the information desk.

The NR blurb about the Christmas work mentioned more OHLE wiring at Lime St.
I can't think where that might be.

Travelling over the newly resignalled area today (Speke-Allerton), the new signals are plated WE (is that Weaver Jn-Edge Hill?).
It's also obvious that not a lot of preparation has gone in to the remaining resignalling at Edge Hill (eg no new foundations for signal posts).
I also didn't notice any improvements in track layouts or crossing speeds, but you can go south from P4 at Parkway now (except they have dismantled the temporary platform extension which Virgin used during the blockades!).
Both old signal boxes have been de-named, but are still standing.

Be careful.. can you? There was always the option to head 'south' from P4 around the curve into the freightliner depot at Garston but not South towards Ditton.

I say this only because a) I have made the same assumption before and been told off for it, and b) I was led to believe there was to be no track and or signalling changes, beyond the resignalling 'as is' due to the added risks to the program that would have entailed.

Duly noted!
I'd better wait for a new track diagram.

You still can’t go south from platform 4. The signal controlling the move around to Garston also appears to have moved much closer to the platform ends, which might preclude any future temporary platform extensions?

Well why is there a "feather" on the new signal on Platform 4?
Futureproofing, perhaps?

As Tomnick points out, the only route which can be set from signal WE9806 is to the reinstated Garston chord;
otherwise the signal acts as a glorified 'fixed red' for trains terminating the Liverpool direction.

Is the feather in the same direction as the Garston chord? Signalling standards require one for a diverging route if there is a track straight ahead, even if there is no route onto the straight ahead track.

It is indeed, and yes, that’ll be exactly the reason for it. The turnback signal from the Up Fast platform has two feathers for the same reason.

Edge Hill is only a recontrol, so there isn't a huge amount of ground work if I remember correctly. There is some minor changes, but nothing on the scale of the re-signalling of the previous Allerton and Speke Junctions area of control.

For the purposes of clarifying things for people reading this part of the thread, what does "feather" mean in this context?

The light above the signal which shows the route set. Straight up - straight on; diagonally to the left - diverging to the left; diagonally to the right - diverging to the right. Driver needs to know as there may be different speed resrictions, and he will want to know that he's being sen t the right way!
