Railway Ballast Cleaning Train - Part 6

It looks like a diesel shunter but, in fact is a 440V electrical power generator wagon for the ballast cleaning machine conveyor motors etc.

There are more details to add to this wagon that will have to wait because there are dependencies on parts of the ballast cleaning wagon that are not yet modelled. In particular, its spoil expulsion conveyor that rests on top of the generator during transportation.

The black radiator grill has a close mesh effect that was created using a trick of the 3D printer. When it prints thick parts it prints a honeycomb for internal layers to save on plastic and print time. I simply programmed it to continue printing the honeycomb through to the outer layer instead of finishing with a solid layer. Parameters of the honeycomb can be manipulated to give the desired close mesh effect.

The two lamps required some ingenuity to make from bits to hand. They were made from the clear end of a Bic biro ink tube and the dome formed by filling the hole with polystyrene cement gel. I was pleased with the outcome until closer inspection of the prototype showed them as being oblong!.
