Hi. 

I intend to use Kadees, probably in conjunction with Parkside NEM mounts on extensions from the bogie pivot points. However this will take a little bit of experimentation. I could also try Kadees mounted directly under the bodies, but I suspect I will have trouble with the tighter (radius 3) curves on my layout.

The 456 will remain a 'dummy' unit for the time being, but I may possibly motorise it at a later date. As such, the 455 will provide the power for the present time.

Classes 313 - 315 and 507 - 508 would be nice but, at the current time, none are readily available in 4mm scale that I know of. I would happily run a 508 (or two) on my layout.

Thanks for the compliment.

Would the Ayjay kit cost that much? Their 4 COR kit is around
