The Cargowaggon twin vans are something I have long wanted to see produced in N.
We are proposing three livery options, original with Cargowaggon markings, Perrier, and revised Cargowaggon with yellow painted ferryhooks and loops and circular warning labels on the doors.
As has already been pointed out, these are as useful in block trains as they are in ones, twos or threes in enterprise type mixed trains, and they have been seen from the Continent to Cornwall and Scotland.
This shot by Mick Page, posted with permission, shows an Exeter-Mossend train in 1992:
At the moment we are focussed on N Gauge for this model, and while I can see the attraction we won't be offering any further 4mm models until we have delivered the 00 TEAs to the market.
For N gauge enthusiasts we will be adding the order options to our website in the coming week.
