The Hornby Class 66 is in no way shape or form anywhere close to the specifications of the Hattons Class 66. The Bachmann Class 66 is also ahead of the Hornby Class 66 by a country mile. What screwed the Hattons Class 66 was terrible QC and Hattons' absolute lack of communication about it thereafter. At no point in time did Hattons issue a statement about the defective model. The Hornby Terrier wasn't rushed out by Hornby at all. It was an Oxford Rail model that came under the Hornby brand. So no, Hornby didn't duplicate the Dapol/Rails Terrier. The GWR Prairie could possibly be duplication but since Dapol have such long development times, it's hard to say who started first. Either way D*p*l won. They played it slow and steady, and they had the better model The Class 91 was mentioned at Warley 2016 when Hornby announced the Class 800 IEP and Class 87. The Hornby rep at the time of the briefing clearly mentioned that the Class 87 was chosen first as it was cheaper to tool and said that the Class 91 would follow. Cavalex took an unnecessary risk by announcing their Class 91 project. After the Hornby announcement, Cavalex said they received more orders but still decided to cancel their model. The 4-wheel and 6-wheel coaches are the only ones that they deliberately copied. Not the best idea from them. But thankfully the generic coaches are good sellers. Sadly the Hattons ones are delayed significantly. I'm sure they have the better one on paper. But if things end up like the Class 66, then I'm worried for them.
