What Jason is concerned about doesn't come close to a  S curve that would cause problems especially in  N Scale since the majority of the cars have truck mounted couplers.

Whether an S-curve is the source of problems or not is entirely a matter of the specific geometry of the track and the rolling stock.  Truck mounted couplers are in themselves another potential source of problems, esp. in cases such as mismatched overhangs, or pushing/backing the train.

If you want to say that's negligible and will never be an issue, that's great.   


Are those MTL heavyweights? If so part of the problem in this photo is that the bolsters are closer to the center of the car instead of being closer to the outside of the car. Still don't quite get why MTL did this.

What part of 9 1/2" radius don't you understand?  :)

That's a good point though, I forgot about that.  I got a couple Hiawatha cars I think I can get to.

And Bryan, is the BL body or truck mounted couplers?

Yeah that made big difference.  I mean if your in between cars when it happens you're going to still become part of a magic act, but it closes the gap quite a bit. And this is with #7s.  If I go 8's or if I can squeeze an 8/10, I don't see a problem.

Thanks Mark. (And everyone else  ;)).

Unmodified, so they would be truck-mounted.  But I've run through my modified MTL Heavyweights with the recessed body-mounted couplers as well.  I just took some measurements with the modified MTL cars - the coupler head offset at the center the diamonds is only .050" off center, .100" total.  You can't couple cars on the diamond, but you wouldn't do that anyway.  And the offset would be less with passenger equipment riding on trucks with a centered bolster hole.  So it works fine, with plenty of leeway left in the coupler swing.

Except that the issue was how cars with body-mounted couplers would be affected, which is a legitimate concern.  Many people, including myself, convert their equipment to body-mounted couplers.  Nearly all motive power today comes with body-mounted couplers.  So I can understand the concern.

I will say I'm a little confused.  On Train Board Brakie wrote:

That should be everybody's goal. "


But this thread is wasting his time.   :?

Jason,I will reenter this whoop de do to answer you concern.

Indeed derailment free operation should be everybody's goal..

I see absolutely no issues with that supposed "S" curve-such set up of switches works quite will in HO and it will work in  N just as well.

If it was a problem setup I would have told you in my first reply.

Do what you think is best for you.

Is it really so hard?

I do appreciate your input, so thank you. But if you can, check your baggage at the door.
