When Accurascale announced there was only the Hornby Class 31 around and they haven't really seemed to pay much attention to it for quite some time that there are still big gaps in what they've produced from tooling thats nearly 20 years old.
Bearing in mind Accurascale announce when they've got something to show for it, as in Engineering Prototypes, it wasn't just a CAD drawing so it was obviously well on the way to a finished product turning up. I can only assume that Bachmann must have been at a similar stage at that point and to have spent the big money on tooling already that they needed to continue to recover that.
