LNWR, Observation Car, OO
Welcome to this LNWR rolling stock build or should that be design. I don't normally enter competitions as the standard is very high especially here, but as I had this started, I thought it would encourage me to finish it.
This journey started two years ago, replacing some old scratch built items, one of which is the LNWR observation car, I obviously by my username model the Bluebell Railway, and one item of rolling stock is usually on the end of set's every time I attend.
So why this particular carriage? As far as I am aware there is no kit for this particular coach in 4mm or OO, instead of scratch building this, I feel not just to benefit me, but others also I would try go down the 3D print route, but this means a lot of research, and the best way to go about it.
Two years ago, I started researching, contacting the LNWR society for any available drawings of the observation car, they managed to find one, but no measurements. Thanks to some contacts on the Bluebell Railway, they kindly helped me out with detailed photo's and a few measurements.
(A selection of research images)
With basic measurements I could start building the coach in CAD, for this I turned to a nice simple 3D software Google Sketchup, I am not an expert at 3D design, and I am sure someone who is more experienced than I could do a better and faster job, which is why it took 2 years. This model will be printed to 4mm scale OO, which is what I model in.
Due to its length and complexity the body was divided in to 3 sections, 2x ends, and 1x middle, details for the roof were added details, as well as an interior were all printed separately, to aid quality. The chassis was printed in a different material which will be dyed black, to aid painting, this is a flexible nylon material, which has similar characteristics to plastic but just cannot do the detail.

More soon next time.
