Reverting back to hook & horn couplers?

[rrinker]

The other option is to resort to truck-mounting the couplers. This is where backing up will suffer, as the forces will try to skew the trucks causing the wheels to pick at the slightest irregularity. This is usually the problem with horn-hook couplers as well, as usually they were truck mounted. Horn hooks have an even stronger spring pushing them to the side, so this makes the condition even worse
