No brakes

[crstagg]

[QUOTE=prr4ever;1872764]yeah Geoff,


However it still seems to be a strange OR thing. I made a whole new consist different engines, different rolling stock, same thing no BC pressure in the first ten or so cars behind the engines, random pressures in the rest. Wierd. [QUOTE]

Did you use the same Engines? How about posting the ENG file for the last ENG.

[crstagg]

From your OR log:
Warning: Cannot parse the constant number 27.2.2 in C:\AA MSTS BASICS 40-50\Train Simulator\trains\trainset\50ft Boxcars AM\SOU584845.wag:line 77

How about posting your ......\50ft Boxcars AM\SOU584845.wag file.

brakes

Charles,
The comment lines are not mine, I do not put comments in files. However at one time I did use Route Riter to set up all the brakes. RR appears to have added all the comments.

I apologize for different files. I have been changing out cars in the consist and may have posted a different wag file. However no matter what I use the brake actions are the same. I just re-posted a common brake set up I use for rolling stock.

Engines do not seem to matter. I will post an eng file for the current consist which is still giving me the no BC on most of the forward part of the consist.

I looked at the amsou box car. the brake values are very poor. No time today to zip and send. I will update the car and get back tomorrow with the original wag as it is now, before I update it. It works in MSTS so I had not really noticed it till now.

Well, I owe an apology to all the folks helping me with this. It is resolved and it is something I should have checked first. :-(( A special thanks to Charles and Geoff who got me thinking on the right track.

The problem was the brake values in the wag files...

I got to thinking and remembered a year or so ago I used Route Riter to batch "correct" a good number of my wags. I noticed that the wags with all the comment lines in there and realized those were the files that RR had entered. So much for that mistake. I looked at all the wags in the consist that was in question here. Quite a few had very poor brake values as you guys pointed out. Edited them all and now the brakes are fine in OR and MSTS. (Horray!!)

I do not know why they worked OK in MSTS and not in OR.

Now I have about a zillion wag files I have to look at and correct...(Oh no!!) Anyway it will also give me a chance at the same time to update the sound files.

I do have one last question, for now)....

In the OR F5 view extended that shows the individual rolling stock brake values there are only 25 cars in view. Is her a way to scroll through all the cars brake values? It will help me start to find some of the brake bad guys if I can have a brake cylinder pressure readout on each car.

Again, a big thanks to all you who helped me resolve this!!

Dave,
pit would be of interest to know which version of RR you used.

Hi Dave,

Good to hear that you have the issue sorted (even if it means a heck of a lot more work for you to fix). I still believe that MSTS has bounding values for their variables so that if something was written into an eng or wag file that was way off, MSTS would ignore it and insert its own value. OR on the other hand wants to use what is written in the eng/wag files and operate based off of those values (however screwy they may be)!

Just downloaded X3415.

Now have more cars shown in F5. still not whole 75 car consist however.

[prr4ever]

Thanks Geoff, you mentioned that in an earlier post here. I suspect that is correct.

[R. Steele]

Now I have about a zillion wag files I have to look at and correct...(Oh no!!)

That is just what I have been doing, examining and editing all the files in the trainset, using a combination of tools....just makes sense when OR will give very realistic performance when presented with true values.

I do have one last question, for now)....

Known problem, I have read threads discussing different approaches, nothing appears decided upon. Last thing I read was some kind of html or some other file accessible/editable during the simulation. If I remember correctly.

Very happy you got some brakes, hard to stop without them.

[prr4ever]

Good to know it is an issue and not me. Not that I want them to have issues!

brakes

I am working on the N&W wagon, I have taken a Reading box that works fine in OR and MSTS. I changed it's wag to have the brake values I have used for years. No brakes. OK put the original back, brakes work.

Tried both brake values in the N&W hopper. Still no brakes in OR on the N&W Hopper. The zips are attached. The brake values in the Reading wag are the ones that function in OR for the reading.

The values in the NW zip do not work in OR when placed in the Reading wag.

The values in the Reading zip do not work when placed in the NW wag.

Sum it up.
1.Reading brakes in the zip,work fine in the Reading as it is in OR and MSTS

2. The N&W brakes do not ever work in OR with either brake values. Work fine in MSTS.

3. The reading brakes do not work in OR with the N&W brake values.

Confused??

I have compared everything in the wag files and they look normal.

The brake values in the attached N&W zip are those I have used for years in MSTS. Going to get away from here for today. Tomorrow I will try some totally different rolling stock and see what they do.

No Brakes

I have been working through a short train set to find why some rolling stock has functioning brakes and why some does not. The most common thought seems to be how OR reads the physics vs how MSTS reads them.

So, here are two wag files on two separate cars. Other than for some different values in tonnage, shape files etc I can not find a difference.

Both cars have good brakes in MSTS.

The BNgon works fine in OR.

The D&H 40ft box has no brakes at all in OR.

If I can discover the secret to this I will be a happy camper!

[crstagg]

Why is the D&H Mass 30% less than the Empty weight in the comment?
Wagon ( D&H40ftb_18652
comment(D&H 40 Foot Box Car)
Type ( Freight )
Name ( "D&H 40' box car #18652" )
WagonShape ( D&H40ftb_18652.s )
Size ( 3.1m 4.6m 13.65m)
comment( 28.03t empty, 160.747t full )
Mass ( "19.6t" )

BTW
the Brake values are exactly the same for both WAGs.

Maybe it has something to do with adjacent WAGs. What is the composition of your consist?

[crstagg]

Why is MaxAuxilaryChargingRate so low? Default is 10. Typicat Setting is 5 or greater. Your setting is 0.27

Hi Dave,
Just comparing the two wag files :
BNgon_box has buffers, but D&H40ftb doesn't - don't think this will cause problem, but you never know!
BNgon_box has correct Damping parameters (N/m/s), but the D&H40ftb values are incorrect - N/m - this is my chief suspect!
Friction values are totally different between the two, but I doubt if that will cause lack of braking. Try substituting one set for the other.
BNg0n_box has its Name before Type whereas the D&H40ftb has it after - again, I don't think it'd have any detrimental effect.

Cheers,
Ged
