Thanks to both STG and gitter. I've read a few of the previous posts on this problem, and I'm quite annoyed with Hornby. I agree with one writer that Hornby need to seriously review their Quality Control! If there is someone from Hornby monitoring this, I suggest you reply to this issue. There is NO REASON for anyone buying your product and running it on your track/points to have any problem. There are sufficient posts about this same problem to send up a red flag to your quality people. We SHOULD NOT have to make adjustments to components to make them run smoothly. I have bought your products in good faith, and will continue to do so, as long as you are receptive to problems we raise, and take appropriate action. This issue clearly indicates that you have NOT taken appropriate action, and continue to sell products WITH KNOWN FAULTS! That is ILLEGAL in Australia, and I'm sure the UK has similar legislation. I look forward to your prompt - and positive - response.
