It's not so much a lack of updates. There's total silence. On the 91/mk4s Andy York shut down the OO gauge thread on RMWeb and invited Cav and Alex to set up a new one for the N gauge one. They didn't. There's not a single update on their website anywhere. Not even a spec, it's just "at design stage".

I ordered some of their PGAs which they then formally cancelled, but everything else just sort of fades away. I get not doing N gauge, it's a smaller market and tougher to get the volumes I'm sure, plus the OO gauge set will obviously pay more, but the persistent "yeah, yeah, we're doing N gauge" annoys me.

I will certainly be interested in picking up a few of these when they are eventually released. I am a fan of the class 56 and it was the Dapol class 56 release along with the announcement that they would be doing the class 142 Pacer that tipped me over the edge into N gauge all those years ago!
