Class 92 on sale

[gptech]

the europorte one still has the EWS Decal, is this correct and authentic?

I wouldn't think so...

Edited to show correct picture...

[gptech]

To get rid of the EWS logo double click the loco in scenario editor and change the number in the right hand flyout box. Use a blank texture such as 'V' for the second letter after the numbering ie: 92008xABC would become 92008xVBC
Using the same letter for the 3rd letter after the number gets rid of the BR arrows.

There's nothing wrong with the reskin as such, but it's calling for the default numbers from the .bin and .dcsv files rather than having it's own dedicated set that automatically hides the bits that you don't want.
Drop Jack at Rockrail a message and get him to get the reskinner to have a look at it.

That's something I didn't anticipate, DTG actually having something that's dynamic and changeable.

Also yyyyamst I thank you for the knowledge that is diamond in these matters to get a real insight

Thanks for the info!

The "4th letter has to be either Z or Y, but I can't see what this controls ?

Z is a blank texture, Y is logo_2 according to the digits.bin file.
logo_2 itself shows in RSBin Tool as SNCF, but has a totally black alpha channel making it invisible too!----a clue as to a possible future variant?

EDIT: 'Un-hiding' logo_2 by deleting the alpha channel completely as a quick test gives....

In simple terms - what is the "alpha channel" we have to delete to make the SNCF logo appear and where is it?

Thanks

Class 92 logos_2.tgpcdx is the file you need.

Open in Photoshop, go to the channels palette and paint over the alpha channel in black. This should make the logo invisible.

[johnmckenzie]

I was thinking why this should be hidden but present and then it struck me - has DTG got an SNCF license on the way? If so, does that mean a French route in the pipeline?

It's already black, that's why the SNCF logo is usually invisible.

I removed it as a quick and dirty test, to do it *properly* means creating a new layer, with white areas just corresponding to the parts of the texture sheet you want to be visible.

Give me time to have my tea (and more importantly, feed the cat) and I'll do a proper job and upload it to the library.

Replacement (or rather additiuonal, as it lives outside of the .ap and doesn't need the original file deleting) file at:

https://dl.dropboxusercontent.com/u/713 ... F_Logo.zip

Simply extract the contents of the .zip into your RailWorks folder, and away you go; any class 92's that are numbered 92xxxxxxY will now show the SNCF branding.

Peter, the alpha channel is part of the .TgPcDx file itself and to edit it you need to convert that texture file to .dds. As far as I know Photoshop and PaintShop Pro both allow the editing of channels, and I'm sure there are many other image editing programs that do the same but I've used DXTBmp (http://www.softpedia.com/progDownload/D ... 53836.html)

if you imagine the texture you want to edit as being drawn on a piece of paper, the alpha channel is akin to a piece of black paper with bits cut out which you place over the top---where the black isn't, then you'll see the texture.
As you can see from the image above, doing the job *properly* gets rid of the rectangular box effect around the texture, though that is handy if you're trying to replicate a sticker!
With DXTBmp, you first produce a black and white copy of the texture using whichever editor you feel happy with, flood filling areas with white or black is often all that's needed. if you 'go over the edges' a bit with the white it isn't going to be noticable if the background is a close match to the colour of the surface the texture will sit over so a great deal of care isn't needed in many cases. Save the image as a .bmp file and use DXTBmp now to open the texture you're editing and import the .bmp into it; save it and you're done. (In theory anyway )

Thanks Gary. I appreciate the answer but I will use your file to make the logo appear.

A question about the Class 92 Brake Gauge - which I think yyyyamst might be able to help with.

When you release the brakes to 5 Bar there is a needle around the outside of the gauge which moves quite fast and another around the inside which moves slower.
I presume the inside one shows what the pressure is but when you brake the outside one moves to what you have set the brake to but the inside one barely goes below 4 Bar.

Not sure if this is what is supposed to happen or not.

No, this is not the way the real one works.
The little arrow needle around the gauge is the Equalising Reservoir, the other needle is the Brake Pipe one. The brake pipe gauge is far too slow!

This must be a bug in the script... but since the scripts are .out ( ), only the author is in measure to make the correction...

The small Needle is the Control Air supply. The PBL uses 3 different Air pressures, 2 are set at a specific pressure and the other is variable. When the Auto Brake Stick is held at Release, this activates a Release EP in the Brake Control Unit. This allows a 7 Bar Air supply to feed a Transmission Unit and also the Control Gauge. Inside the Transmission Unit are Diaphrams. The Control Air lifts the Diaphrams and opens an inlet to allow a 10 Bar Air supply to flood the Unit and feed into the Brake Pipe. The Driver will see the Control Needle rise followed by the Brake Pipe pressure. On long Trains the Control Needle will shoot up to 5 Bar and the Brake Pipe Needle will slowly catch up and match the Control Needle. Going back to the Transmission Unit, the Diaphrams are mounted on a Stem Valve, basically a hollow Tube. This incorporates a Spring set Valve which is set to close at 5 Bar (Brake released in the Brake Pipe). The Driver will now see the Control Air Needle and Brake Pipe Needle match each other. When the Brake is applied the Control Air is vented which now causes unequal pressure in the Transmission Valve. The Diaphrams are pushed down and an Exhaust port is opened. The Brake Pipe Pressure is vented through this Port. This is variable and totally governed by how long the Driver pushes forward on the Brake Stick.
The Auto Brake Stick will only drop the Brake Pipe down to 3.4 Bar. This is ample pressure. If a Driver finds he needs to reduce the Brake Pipe further then something is wrong which is either a Train issue or poor driving. The Driver must always carry out a running Brake Test ASAP from starting out. This involves accelerating up to speed and making a Brake application. By noting the amount of reduction of the Brake Pipe to speed ratio and the feel of the Train at that point, the Driver will have a very good idea of exactly the Braking capability of his Train.

The best representation of the PBL Brake is on the Class 60. The Class 92 in Train Sim works in opposite, Control Pressure drops before Brake Pipe! Something we will have to live with it seems.
Hope this helps?

Yyyyamst,
I am usually pretty good at remembering to do a running brake test when I take control of a train at the start of a scenario, upon changing ends or after attaching/detaching (my collision experience in real life at Walton on the Naze on a Class 58 tour lives long in the memory) etc. Is there a minimum speed at which a running brake test must be undertaken? The reason I ask is that upon starting the Electric Troubles scenario, the first few minutes of movement are out of the yard at 5mph for some distance. Though I did a running brake test, it seemed of little value at 5mph...

Also, is there a minimum speed reduction to aim for when doing a running brake test? I normally aim for a 10% speed reduction but not sure what would be expected prototypically. What are you watching when you do a running brake test? Are you watching the speedo, the brake gauges or just getting a feel for the train? Or maybe all three at once?

Anyone proclaiming that men cannot multi-task is lying... We just choose not to a lot of the time to make the 'others' feel good

Please can you guys let RSC/DG know? I appreciate they may well respond with the usual "it'll be considered for possible future updates", etc. but if you don't ask and all that...

Thanks,

Rik.

I Know of the real workings and I thought it was wrong. The Class 66 v2 seems to work correctly.
