Thanks both - unfortunately I didn't use bearings. I'll know better next time!

I enjoy making these kits, but have found the issue with "soft plastic". Out of the three I made, one only ever has three wheels in contact with the rails, which results in it derailing regularly. That really put me off making more, but I'll keep an eye out for original Airfix kits at future shows (though I'm not sure the decals will have aged well)
