Yes, my coupler is absolutely perfect for this scenario, even if you’re not looking to fully adopt them. Based on the pictures you posted, you’ll be able to perfectly drop my UGS series couplers into the Bachmann Hudson with full functionality, no modifications needed at all.
Here it is installed on a Bachmann consolidation, which is definitely not exactly drop in, but ultimately looks great since you don’t have a massive pilot hole either. Considerable improvement over the stock dummy thing the consolidations come with. Not the same model of course but indicative of what to expect.
I want these on the market ASAP too, believe me. I need to start earning back at least something to fill the massive black hole of costs I’ve accumulated so far in this venture. Never been closer, more (good!) news to come soon.
