Is it me or does other people have problems with Hornby quality control. I’ve just purchased a Hornby large prairie, all fine with running in then suddenly it derailed, investigation showed that the problem was that the screw holding the front bogie had worked loose and become detached from the lock body. Now got to find the missing screw on the layout and hopefully attach it properly but my point is that this should not have happened in the first place and is due to poor quality control!
