Yeh it fits fine, both ends of same wagon kept coming out..... replaced with Bachmann couplings and no probs.... tho two couplings with wagon don’t go it to anything so they are problem and are in bin, other 4 are fine so far and I’ve 12 more coming from various shops so let’s see if any more rouge couplings..... I can’t reiterate what a brilliant wagon you have done.
