Looking for a particular type of UK 4 Aspect approach colourlight signal

[shaneturner12]

Hi Trainzers,

Perhaps someone can help me out here.

I am looking for a UK 4 aspect colourlight signal that has an approach facility, preferably one that is able to do flashing orange (which is a type of caution).

There is an example of this just outside Acton Bridge station in the UK - I will see if I can find a picture of it if requested.

I am aware of the ones in the UK Signalling pack by snowsignal (which I do have), but they have a scripting fault that causes buffer overflows.

I will be grateful for anyone who can point me in the right direction.

Will these be of use to you Shane... These are on Blodnocks site.

Hi Stationbeem,

I will have a look. I've got that pack installed on my version so I can check easier. I haven't yet seen an approach one in the pack yet, but I haven't checked every single signal yet.

Thankyou for the suggestion though.

As far as I'm aware only snowsignals pack supports approach control and flashing yellow aspects .
The current built-in signalling script doesn't support UK colour light approach control or the ability to set up flashing aspects that are specific to a route (in conjunction with the VSR feather system)
Bloodnok said that at some stage he may look at implementing the system into the built-in scripting . It would be nice just to have to place a feather board that sets up flashing yellows / approach control .

The only other way would be to find someone with the knowledge to sort out a compatible script . The script is required to override what aspects are actually shown at the signals to us when driving or observing , The AI still See's the signal as a standard 3 or 4 aspect . It would also require some way of holding a signal at red (with that applying to AI trains as well) until the train was at the required distance from the signal and then changing the signal to a less restrictive aspect if the line ahead was clear .

I had a feeling that may be the case. I would use snowsignal's signals if it was not for a major buffer overflow problem, that Railwaves never fixed before they went out of business.

I will see if Bloodnok is able to sort something out along those lines, as I would like a prototypical signal in the area mentioned in the first post.

Thankyou for your answer though Dave - it is appreciated.

P.S. How's things going with your WIP projects? I haven't seen much from you over the last month or so.

Building work at home over ran just a little bit .....
Hardly any spare time to do anything other than quick flits in and out of the forums etc .

A TS12 service pack with some new built-in signalling features would be a nice crimbo pressie from NV3 .....

There's a fair few junctions / crossovers on Midshire that could benefit from approach control / flashing yellows .

 

[shaneturner12]

Indeed. I've also got a couple of places that could do with it as well.

It would be nice if they could implement subsidary abilities with the signals as well, as that would benefit one of your assets as well.

Shane

P.S. Hearing about building work seems to remind me of the programme Cowboy Builders on TV, although it's probably completely unrelated.

 

[johnwhelan]

Would ATLS handle this?

Thanks John

 

[shaneturner12]

Not sure. I haven't had much of a try with that yet. I always thought that was for level crossings though.

Subsidiaries : Got numerous signal designs I'd like to build but there isn't much point if we can't get the indications to work , I'd spend more time on the forums explaining why they dont work than in the Sim itself .

Cowboy builders ..... Not far off , the first plumber we employed caused all the delay and more problems than he was fixing !
Quoted 3 day job became a 4 week nightmare and not all the required plumbing work was completed !
He was told to finish when only part of it was complete as we'd had enough , Tried to overcharge us as well though he didn't get anywhere with that !!
For the second plumber we used a Sandwell council recommendation website and he was superb and got the rest of the plumbing jobs done in a day .

Most of the work is done now and there is light at the end of the tunnel , just need to sort out an enclosure for the combi boiler and a bit of painting . Hopefully finished before Christmas

 

[shaneturner12]

That sounds interesting...

As for your plumbing, hopefully that's all OK now.

Hopefully you get it sorted soon, as it's getting colder.

I'm presently looking at Bloodnok's new semaphore script, and he pointed me towards the wiki, and the signal script in the trainz scripts folder. It might be worth taking a look there.

Is this the type of thing you're looking for (from trainzdev-wiki):
"If a signal is supposed to be permissive, include state '1' rather than state '0'. The Autopilot will now treat it as a permissive signal, and drive past it, queueing up behind the train in the next section."
It also looks like the there's a tag in the config for making the light flash......but I haven't tried it so it might be something completely different.

Thankyou for the info Chris. I will have a look at that later on today.

I think the problem with subsidiary signals e.g. backing and calling on, is they shouldn't apply to all trains, and would therefore need to be controlled by a drive or path rule. Or a manual trigger if driving in cab mode.
How much fun the AI drivers would have selecting routes if they were all allowed to pass red signals.

Chris.

 

[shaneturner12]

It would be interesting.

As for the Approach Control bit of the problem, have you tried this?
Set up the "default route" through the junction to either leading onto a turnout set against or a dead end, using invisible track & lever if necessary. This means the controlling signal stays red, and does so for AI as well.
Only set the route through the junction when the train is close, either by a trackmark just before the signal and a Drive To (not Drive via) command, or a trigger and a Path Set type command.

I know in TRS06 that indivisual junctions revert to their default setting after a train has passed - not sure if the same in true in later versions. My route has all junctions set in this manner (leading onto a dead end) and so all junctions are "approach controlled" to AI, even when using a Drive To command several junctions ahead. Which is why I use Path Set commands!

 

[shaneturner12]

I will have to remember that...

Meanwhile, I have an interesting development regarding subsidary working (you may call it a bit of a breakthrough)

I have been playing with a personal-use modified version of nexusdj's Sig 1a dorman fixed red & subsidary signal, and have managed to get it (with a few modifications in it's config.txt file (an excerpt of which is available on request) which now displays a red + subsidary aspect when the junction ahead is set for the siding, and standard red/yellow/green (depending on train position) otherwise.

I have one question though. Is it possible for a signal to display green as long as the junction ahead is set correctly, regardless of whether there is an approaching train or not?
