Thanks Stephen. Most of our layout curves are 900mm radius with a few 750mm, do you think the Kadee 17 or 18 might work ok? I'm not keen on the visual intrusion of the drop bar on kaydee's, but like the narrow coupling. Are there shorter versions of the Bachmann tension lock style couplings that would pull coaches closer together? I suppose I could cut off the kaydee drop bar on couplings between coaches and leave them on the end of rake coaches.

EDIT: Apologies, just found this post http://irishrailwaymodelling.net/showthread.php/2268-kadee-s-and-Hornby-couplers
nirclass80 video gives a great idea. I could cut the drop bars off the couplers between coaches and just leave them on the two end coaches of each rake.
