Nice idea Matt. I hate to use offset couplers. In G scale, they will fail on a heavy train dipping at the end and uncoupling. It would be much better to just use a shim than the offset. Lowering the car would be ideal to help all issues.
I wonder if the new series 2 rail trucks are the same height? Probably are when I think, as I type this. Duh.
The long-shank couplers are actually a higher risk if there's plastic involved. Had to replace the couplers on some Atlas 89-foot flats as the Atlas shank was plastic and would shift up or down under heavy load. Replaced them with Kadee's which are metal and used metal draft boxes. Was able to use the Atlas spacer plate with new holes drilled to properly position the Kadee box.
Well, this might save me some. I already put them on a few cars though.
Long trains in G scale seem to make the laws of physics appear. If something can fail, it will.
I haven't had much problems in O scale in my basement yet. I bought too many engines so the cars I have, don't tax them very much in big consists.
I have noticed that the older Atlas couplers will either come uncoupled, or break. I haven't replaced very many of them yet. I put up with it for a few years now. With pushers on a train, nothing fails.
