They were featured in the 2005 brochure and due to be launched last year. Snag is that there is a whole heap of other promised models for last year in Bachmanns 2005 N gauge catalogue (such as class 101 dmus, HST125 sets, class 168 Clubman dmus, class 60s, class 44/5/6 Peaks, class 42 Warships, Pullman and Mk4 coaches, HTA and VGA wagons) that didn't get launched.
No doubt they'll form the backbone of the 2006 brochure and promises. So perhaps, fingers crossed, with luck, god willing and hopefully, we'll get to be able to see and buy them sometime this year. But don't hold your breath.
