I'm all for it. Bachmann's tooling is aging now. And yes, whilst it's still a good model, there are some drawbacks to it that are starting to age considering the other models that are coming out on the model. My main gripe at the moment about them is the headlights. The lack of marker lights on both the 'original' lights with the rectangular markers through to the newer LED-style is quite a major thing. You only need to look at some other models like the Hornby 67 or Bachmann 150 where such things exist, although those models also have their own gripes. The Hattons model is catering for all variants, from cab windows to bodyside differences.
Looking forward to the release and seeing how it works out.
