Couplers actually coupling

[Trainguy76]

Hi, I'm trying to get a wagon I just got in game to work, and I am not able to have a loco couple to the wagon? I have the coulplers referenced in the blueprints, and I can see them, any ideas?

[Kariban]

I can only guess that the couplers are inside the collision box, so the engine is hitting the wagon itself before they get near enough to couple.

[Trainguy76]

Well, the loco will pass by the couplers and go (nearly) through the wagon, so i can't imagine that's the case.

[Kariban]

Hmm. Obvious question time then.

Are you using the same coupler blueprint as the engine?

[Trainguy76]

It's the default ES44AC, and yes.

[Trainguy76]

What if the couplers are at different heights? The wagons coupler reaches the top 1/4 of the engines coupler.

I got this to work, I needed to modify the pivot points, which I though would be where the bogies were.

[Kariban]

Right pivot points are where they pivot around ( obviously ) when they go around corners, attachment points will be where they sit when coupled. So I guess they were inside the collision box?

I think - without checking and it's not like I looked much - each coupler has a collision box of it's own defined in it's blueprint, and obviously they will have to collide to get it to couple.

What should the size of the "collision box" be? From buffer to buffer? My wagon is 26400 mm from buffer to buffer. So should the collision length be 26.4 with the pivots 13.4? If I choose that, my wagons don't couple tightly together and there's quite a gap.

[Trainguy76]

I think, from my little experience that moving the pivot points in the main blueprint to be shorter would handle the large gap between cars.

Hi,

The "collision length" is the Body excluding the buffers.
If you include the buffers with the body length and divide this in two you have the pivot points for Front x and Rear x.

Bringing pivot closer to collision box did make it tighter, however when I uncouple them from the loco they kinda jump off, as if it was coulped with a high tension. When pushing back with the V200 engine, there's a good 20 cm between the engine's buffers and the wagon, and I do get to hear the clunk sound of hitting the buffers. And I cannot get them to couple back to the engine (was able to once though, but cannot remember my settings back then). Same goes with the coupling between the wagons. What blueprint setting could this be?

EDIT: oh wait, excluding the buffers. Pushing with the engine then will make it go through the wagon's buffers, but at least I can couple and uncouple without tension problems. I guess I'll have to fiddle with the collision numbers to make it look "natural" Thanks again for the 'englightment'!
