Could someone who is following this train-sim.com thread summarise (translate?) what is being said?

How effective is this with our UK stock mike? Have you tried it and is there much improvement over the official patch?
Cheers,
Stewart.

I havent tried this version,but basically what i does to my understanding is to modify the Default.wag file.This i believe is the common setting value for all installed stock.

It includes a back up file,which installs with the mod,so you really don't have much to lose by trying it.

I've just written and tested several Skipton activities with extensive front coupler use and only one crash. I also used the front coupler a fair bit on the Cambrian and only encountered a few problems. It all comes down to the coupler settings. I've even written a set of shunting activities for the Skipton route based around the lime works at Stainforth in which you are repeatedly required to pick up wagons with the front coupling. I tested these activities several times without a single problem.

And which fix did you use? This IKB recommended new one or the original? Or no fix at all?

I didn't reccomend it ,i just posted the link for information.A lot more goes on over at train-sim.com technically,so i thought someone may be interested in whats happening with the front coupler issue.

Personally ,i use the the m/s parameter in my damper values for the couplings and that cures 99.99999% of breaking problems.

I have tried both the hacks found at http://www.train-sim.com/dcforum/DCForumID3/18998.html and find the front coupling crashes very frequently after installing each in turn. The same sadly is true whether the 'fixes' are applied or whether I revert to the original default.wag- crash, crash, crash all too frequently. Different users seem to report varying experiences here, though I have no idea what is causing the diversity.

What fix did you use? I am having repeated probelms with your, and other, activities on the Skipton Carlisle CD.

You may be interested to know that even using a different track texture on a route can cause problems with front couplers.

Now as bizarre as that may seem ,i proved it to myself with regards to Pat`s Skipton 1920`s route.

In that i changed all 5 textures relating to track\tunnels from Pat`s default to the KHP2 files.

After doing this i had many problems with coupling to consists,even violently bouncing off wagons and shooting them and loco up in the air.

I reverted back to the supplied track\tunnel textures and everything worked like clockwork.I did not modify,change or tweak anything else.

At the moment I cannot make sense of the whole problem. On S&C 1920 I run activities that use front coupling that operate almost perfectly (eg "Bonnie Face to Bradford") and activities that use front coupling that crash the system at every attempt (eg "Carlisle goods shift 1, part 1").

Now I noticed something the other week Mike.

The Default textures for S+C Default route are 512X512. But the "new" ones are 256X256 plus some of the other routes use 256X256 as well. So it may be a texture size problem ?

Will have to try and get a coupling problem now

Can honestly say I (as in me personnally) have not experienced the problem.

Since the patch anyway.

I did not know that Alan (about the texture sizes). Not being a modeller stuff like that doesn't interest me,it either works or doesn't.

I think you might have something there though,because like yourself i haven't experienced any coupler problems since installing the 1.1 update.
Untill i did this track texture swap on Pat`s route,i had gone months without encountering any coupler hickups,particularly after moding all my own stock to use the /s set up in the coupler damping values.

Could you posibly explain this further.

in the Coupler setup there is a value for break which is set-up for n/m

eg.

Code: Select all

Coupling (
		Type ( Automatic )
		Spring (
			Stiffness ( 1e6N/m 5e6N/m )
			Damping ( 1e6N/m 1e6N/m )
			Break ( 1.1e7N 1.1e7N )
			r0 ( 20cm 30cm )
		)
		Velocity ( 0.1m/s )
	)

now the modified version will be. : ---

Code: Select all

Coupling (
		Type ( Automatic )
		Spring (
			Stiffness ( 1e6N/m 5e6N/m )
			Damping ( 1e6N/m/s 1e6N/m/s )
			Break ( 1.1e7N 1.1e7N )
			r0 ( 20cm 30cm )
		)
		Velocity ( 0.1m/s )
	)
