Project Website

Post by leezer3 on Tue Apr 26, 2016 12:30 am

Hi all,
Just to let you know- This 'fork' now has it's own full website. This may be found at:
http://www.openbve-project.net

The site itself is built using Jekyll, and is hosted on Github Pages (Repository for the site is here: https://github.com/leezer3/OpenBVE-Site/tree/gh-pages )

It's not 100% complete yet, but feedback would be appreciated.

I've done some fiddling with Michelle's driving documentation, plus added a complete new section on British signalling and signs.
If anyone else would like to write a brief section on any other reasonably common types of signalling/ signage, this is the sort of thing I'd like to try and get posted there too.

The stable release posted there is Odakyufan's 1.4.3.0 at present, with a link to my nightlies.
When packages are complete (Soon!), I'll be looking to add an official stable release for these builds, but for the moment the previous disclaimers still apply Razz

Cheers

Chris Lees

Looks good, I only had a quick look but in the British Signals and Signs it is written that the AWS magnet is placed 600m before the signal. But I think is should be a fixed distance of about 180m.

Hmm, no idea where that managed to sneak in from Razz

I think I was probably thinking about something to do with semaphore signal spacings, but no comment off the top of my head.
Correct distance is 180m, or 230m on sections of the WCML with running speeds above 100mph.
Obviously though this will vary in practice, although we'd need a 'real' driver to tell us how much......

Will deal with that probably tomorrow. I also need to get Michelle's developer documentation uploaded to here as well.

Other revisions corrections etc. much appreciated.

Cheers

I'm glad you've taken the initiative to do this, Chris. Nice clean design, and the info is well presented.
I've provided links to it from the celtictrainsim site, on 'links' and 'about sim' pages.

Taking a closer look I notice a few things:

-Download > Source Code:
   You have:"Command line buld    For a commandline build, you will need...."
-Play > Britisg Signal and Signs:
You have: "A ‘Home’ signal has a red arm, with a white band approximately 2/3 of the way towards then end." Shouldn't it be: A ‘Home’ signal ...... 2/3 of the way towards the end. 
 
Same mistake with distant signal.

You have: "To release an AWS brake application, press the SECURITY_A2 (delete) key." This I am not sure about but I though the delete key is only for the canceling the vigilance.
  
You might want to mention about AWS magnets before advance warning speed limit signs.
 
The presentation and content is easy to follow and is a nice design. It's good you have a site for your work on the sim.

Thanks gents Smile
Have made some revisions, will have to check the exact AWS reset behavior. (I have a nasty suspicion it may well vary between plugins....)

I'm aware that some of this is found elsewhere, but it seems logical to place it on the main program download.
I also wanted to make this reasonably simplistic, as Anthony Bowden's site goes into a lot of details about the signalling principles behind this stuff, which can be a little confusing to someone who just wants to drive Smile

Edit:
Michelle's developer documentation now uploaded, along with the most recently built copy of my tools.
No 'new' patches, other than the fix for station names with parenthesis in Route Viewer.


Cheers

Mostly a FYI, but somewhat related to the reasons:
I've had a couple of mails back and forth with someone from Debian, and another chap from Arch Linux, and there is interest in getting this into the repositories.

One of the things they want though is a 'proper' website and a complete tagged stable release, hence this Very Happy

Excellent work on the website, Chris.

A few bits of information which may be useful:

The normal distance from the AWS magnet to the signal is 183m (200 yards). Because of locations of pointwork and other restrictions it is fairly common for that to be varied. In my experience when it is not possible to place the magnet 183m from the signal, the distance is almost always reduced, rather than increased. I know of magnets less than 100m from the signal they relate to.

You mention on the site:

"An AWS magnet may also be placed in advance of the commencement of either a permenant or temporary speed restriction."

Specifically, it is placed 183m in advance of the 'Advance Warning' sign for the speed restriction (where provided). Its intention is to draw the Driver's attention to the sign. If there is no 'Advance Warning' sign, there will not be an AWS magnet.

Similarly, in the TPWS section you say:

"an OSS speed trap may be placed... at the start of a speed restriction where the approach speed is at least 60mph, and the reduction in speed is at least a third of the approach speed."

The OSS loop is not normally placed at the start of a speed restriction. It is placed in advance of the commencement, and set at such a speed that if the train is not on the correct braking curve for the speed restriction, the TPWS will activate. e.g. if the speed restriction is 60mph, the TPWS OSS loop will be set at (say) 77mph and will be located in a position in which the calculation used suggests that if the train is not down to 77mph at that point, it will not get down to 60mph by the commencement of the restriction. The idea of this is to get the speed of the errant train down before it reaches the speed restriction - applying the emergency brake at the commencement of the speed restriction itself would probably be too late.

(In practice the assumptions made regarding the retardation the train's brakes are capable of achieving are very cautious, so it's possible to be on a perfectly sensible braking curve approaching a speed restriction and experience a TPWS activation. This is simulated all too accurately on Network West Midlands, and is just as irritating as in real life. However, that's another story!)

I hope this is useful. Keep up the great work.

I know a couple of people who are all too aware of the ultra-cautious speeds on TPWS loops, the new siding at Chadwell Heath had about 5 activations on the first weekend it was in use!

TPWS grids can also be placed on the approach to a junction and are active when the signal is red.
