I have just stumbled upon this thread -- Blackgill is a really inspiring model, and the photos are great. I lived on Tyneside for 12 years in the 1980s and 90s, and have been planning a model of South Pelaw on the Tyne Dock - Consett route for a long time. Porgress is slow (isn't it always), and I have been busy building a set of nine Dave Bradwell iron ore hoppers as well as 21T hopper wagons and steel carriers of various sorts.
For those interested in Tyne Dock 9Fs, I've also nearly finished an EM gauge model of 92060 -- a rather painful experience involving a few bits from a Dapol kit, a Comet chassis, a Dave Alexander tender and lots of time and effort. Its been painted since this photo was taken, but the valve gear still needs finishing off along with a few more details. I have a DJH kit for the next one, and after that I will probably use the Bachmann model as a starting point.
Cheers,
Richard
