May I ask as to what type of couplers were the problem?

Couplers are Roco. They aren't crappy. I like them for several reasons, but the uncoupling pins definitely caught on the turnouts, although not every turnout. And not every coupler caught, so the problem might be that the coupler pockets aren't all at the right height. I tried Roco couplers, too, because they ought to allow more vertical movement before uncoupling, but they presented this other problem. Roco uncoupling use a plunger and the pin can catch, while Tillig or Kuehn use a curved lever which can ride over an obstruction. I'm only speculating here, but while the Tillig's don't catch, the brief upward push might loosen the coupling for later problems. This again depends on proper height of the pocket on the car.

Since Tibi and Bill take care to level the modules we have way fewer problems with uncoupling. But they still occur even with N American knuckle couplers - some don't work well. So it boils down to using only what works on this layout, considering different curve radii, different tracks, gaps in the rails between modules, or even when there's a brief slack in the train when a loco hits a dirty spot on the track. TT Tracks is the proving ground.

Tibi and I really like the old BTTB couplers, but they can't be used for close-coupling mechanisms.

Terry,

Thanks for the review of the problem. I am looking into building a number of modules besides the pair of 3' x 4' modules that we are currently working on, and needing to know potential hang-ups is a must.

Right, here is my two pennies' worth: the experience I have with various types of couplers is only what I observed while operating the modules in the last couple of years.

The Roco couplers on the military train were misaligned and the system does not seem to allow any adjustment. This negates the advantages of allowing more vertical travel before uncoupling. So I would vote them as the worst of the lot. If somebody can show me how to adjust their elevation and vertical orientation, I will be willing to revise my vote.

dileTTante wrote:...Tillig or Kuehn use a curved lever which can ride over an obstruction.
The Tillig/Kuehn couplers are very sensitive to vertical misalignment but they (most of them) are adjustable. If adjusted correctly, they work well, even on our wavy modular layout. If I ever needed close coupling kinematic couplers, I would use them.

dileTTante wrote:But they still occur even with N American knuckle couplers.
Again, if they are adjusted well, they are the best I observed. Sometimes I am tempted to install them on European stock too.

A lot of the local modellers know us or of us. But they still think about us as harmless bunch of weirdos :lol:

The most memorable piece in the community is still Bjoern's GuiTTar Case. :wave:

This was a beauty. It had a bunch a beer reefers and 4 wine cask cars. The last car was (obviously) a Czechoslovakian dining car. It was the highest class train running, with priority over all other trains.

I may have to "borrow" that idea. :lol:

Ah yes, the inebriation express.
