@frobisher Hence the "d" part being in quotation marks. I certainly don't reasonably expect to see Farish doing subclasses beyond the non-AC/AC distinction any time in the foreseeable future. If the only alternative is dredging ebay for the ancient printed side coaches, when everything else for a push-pull rake exists in relatively recent form, I can't imagine the average modeller being stubborn enough to turn down a brand new offering over nitpicks.
There aren't sliding door toolings for Dapol's MK3s either but that didn't stop KMS Railtech commissioning the Inter7city sets.
