I had an early release in December, it arrived broken and would not run. It was sent back and arrived again quickly. It runs smoothly,but in one direction it falls off points. The Ews colour is very different compared to my Hornby and Bachmann locos in the same livery. I do not know enough about the prototype to see if the hattons one is correct, apparently the windows and font seem to be wrong. An excellent model hampered by severe design flaws as well as appalling quality control. There also seems to be no response on these issues, I.e hattons making an apology video or addressing the customers, thanks for listening to my experience.
