Accurascale website images are great and so I decided to take the plunge and buy packs P, Q, R, S and T sight unseen. Couldn't be happier. The detail is excellent and looks quite robust. I absolutely loath tension lock couplers so I also ordered some Accurascale magnetic couplers as an experiment, but they are too short. So I have gone back to Kadee couplers which look good and work flawlessly. For me, KD#18 works best on my Castle Cement rake as 3rd radius is my minimum. Maybe #19 or #20 will be more appropriate for tighter radii. They were super easy to install on these Accurascale beauties. Looking forward to hooking these up to an Accurascale Class 66.
