It'll be interesting to see what Dave Harries has to say about this. He's currently offline so doesn't know yet :D

Sorry to keep you waiting!

I am glad to see confirmation that my home sim (my local station is one of the ones on the Severn Beach route) is to make an appearance once again and with a slightly newer format. I look forward to its release and will, of course, be getting it. Good to see also that the Filton 4-track will make an appearence albeit on an older era and without the 4 platform layouts at Bristol Parkway and Filton Abbey Wood but I know that you can't have everything.

Ah, Avonmouth BHT. possibly the longest standing bug in Simsig history? It'll be exciting to execute a stress free run round for the first time ever.

I don't know, the number of indications associated with it makes me think it'll be an entertaining first train through!

I think a little outline may go a long way here. This might sound vague, and that resembles my understanding of the workings from memory (Its written down somewhere in the Sectional Appendix I believe)

As people may (or may not) be aware, loading of coal trains at Avonmouth BHT is done at a speed not exceeding 1/2 Miles Per Hour. This means that a loading a train will take in the region of 35 mins, train length depending. An approximation that for each meter of train length, it takes around 5 seconds to pass (From memory this works out at something between 0.4 and 0.5 MPH.

In terms of actions as the signaller, I believe, you as the signaller contact the BHT to request to send in a train. I'm not sure if the specify exactly where the train is to go, i.e. which line at the far end, or you can choose. At this point the loco runs around the train.

When the train is ready to load, the signaller gets a call requesting that the train is routed through the specified hopper for loading, at which point you route the train though. The train proceeds through the hopper at a speed not exceeding 0.5MPH

To more answers Steamers point here, I believe that the five indications are a repeat of what the BHT control have set or got indicated to the driver, although Propel might be something slotted with the panel before allowing a train to reverse.

Out of curiosity, now that I have looked at the pictures of the panel that I have, Wil the St. Philips March line be in the sim? As apparently it was not controlled from the main signalbox. A tile on the panel says 'st. Philips March west depot controlled'. I do have a signalling plan from the 80sh (no date) however that does show it signalled. And I have a WMF file of the yards when the HST sdgs were installed that also show signals. I have no idea how accurate the later file is though...

IIRC the depot did feature in the previous (now withdrawn) version of this sim but I can't recall if that included the signals controlled from within the depot. However the through lines in the depot were certainly included so it could be that the SPM signals are included.

The depot has got 3 quite distinctive eras so to speak to it. Initially, when installed, it was a standard two track junction at North Somerset, with the Up and Down Avoiding merging onto the single line over the viaduct and out to Bristol West. There was a number of ground frames. One to access Marsh Pond, numerous to allow trains to access Marsh Junction Sidings (as they are today), and another to access the former up sidings, now part of the HST depot

In 1976, the former Up Avoiding Line was remodelled, and used a former ground frame connection to regain its former alignment. Other than this, it remained much the same

1991 however, things changed, with the ground frames going, and a switch panel opening. This is the layout largely represented in the EXE simulation.

What ends up happening to the St Philips area on Bristol is to be determined, and is going to take careful planning and implementation so it works correctly in all eras. The final method of operation here is yet to be determined.

It may be of interest that there might be through trains via the depot that way over the summer during the blockages at Temple Meads. (AFAIK rumour only at present)

The 1985 GW150 trains from Portishead and Wapping Wharf also went that way, although as effectively railtours they may have used clipped points rather than there being fully passenger compliant signalling.

As far as I can see in the 80sh the line was called the down/up goods and was fully signalled with 4 ground frames. (Marsh Pond, Depot GF, Marsh Down GF and Marsch Up GF).

The ground frame diagrams that I have suggest identical operation as other ground frames with Facing Point Locks, so I can only assume that this would cover it for needing to be clipped. What I don't know about is overlaps. The earliest plan I have is dated sometime after the year 2000

Firstly, I'm really pleased to see that a loader version of Bristol is on the way, so thanks to those of you who have already put in many hours. Being a Bristol boy this means a lot to me, as it's a really interesting and fascinating network - not just historically but even now with the recent changes.

It's a rather strange coincidence that the announcement was made just as I finished compiling a new, modern TT for the current Bristol sim (details coming soon for that - I'm just testing it).

Now then, I can't hide my disappointment that the new sim does not include the four-track section up the Filton banks or the additional platforms at Parkway and Filton AW. These are fundamental changes which I would have thought are the main reasons behind Bristol being re-released for 2021. Or have I misread or misunderstood earlier messages? And if the four-track section is being introduced for an earlier era, surely it can't be that hard to include it in the modern one, can it?!

And one other question (for now ... will it have the option for ARS?

There are a lot of differences between the original 1970s four track layout and the present day one.

Bristol Panel does not have ARS, so I’d have thought it unlikely the sim will have.

When the area controlled by Bristol PSB was moved to TVSC the E10K interlockings controlled from the PSB were decommissioned and replaced with new ones. While this sounds simple, it means that fundamental things like track circuits IDs, signal numbers, point numbers etc all change. The geographical coverage also changes somewhat notably around Patchway.

A TVSC era, with all the latest works would make sense as a separate simulation once Network Rail finished all the work.

If it intends to be just a simulation of the PSB panel then probably no. Although, given the geographically large area covered, even with the relatively simpler layout than some other sims, there's precedent for adding ARS where it improves gameplay (though, given the afore mentioned simplicity [the only complex area being, IMHO, the area around Bristol Temple Meads itself...] the old Bristol sim was manageable by a single player if paying attention)

Never had stones thrown at the box window when I was there, banana skin on the other hand.....

Looking forward to this one, should make for an interesting sim!
