This week, I received the first test prints for an RA class diesel from i.Materialise. Converting the 3D drawings from the R class turned out to be easier than I thought, taking about 1.5 weeks of "spare" time, compared to several months to draw the R class originally.
Although the bulk of the long hood is the same as the R, the RA is about 16 mm longer overall, with the extra length being noticeable in the "front porch", short hood, the louvre panels behind the cab and the fuel tank. The RA doesn't have dynamic brakes, so the vents at the rear of the long hood on the R had to be "blanked" over. The headlights are different too, with two lights side-by-side rather than one above the other.
Note that the RA is presently sitting on temporary dummy inner bogies (3D-printed in blue) fitted with 12 mm diameter wheels rather than the intended 14 mm diameter, while awaiting delivery of drive bogies from Hollywood Foundry.
