Update 2024-07-10: Updated main part and roof to Version 13(a) - with a little more details and easier handling of front windows.

My friend Julius asked me to create this vehicle and provided a lot of pictures, he made in Hasselfelde. The title image shows the H0m model he made.

After use of a polish snowplough in winter 1978 the Deutsche Reichsbahn [2, p. 150] decided to construct some snowploughs from unused narrow-gauge boxcars 1979.

Today the 99-01-99 (built from 99-02-19) is refurbished and placed in Hasselfelde and the 99-01-75 (build from 99-02-21) [2, p. 146] and now numbered as 99-09-75 in Wernigerode.

The construction base was the picture of the boxcar in [1, p. 202]. I used the opportunity to create matching boxcars and published here too.

The TTm-version will be found here [soon].

Printing

Decide if you want to run the vehicle or just use it stationary. I added different lower shields – with small hole and a wider mouth for the running variant.

These files should be printed in resin. I strongly recommend ABS like resin. I print the boxes flipped over (135 degrees).
If you want to add lights print the single lights in clear resin.

Post printing

Insert some wires -- I use a guitar strings or brass -- for handrails and brass for door handle.

I use regular 8,3mm TT scale wheel sets and insert them after a dark primary paint layer, before spending to much time in painting. Even ABS like resin breaks. You can widen the cones with a drill (opening angle 60-70°)

Lights … until today I only prepared for lighting:

Glue dark material or aluminium foils in. Add lights from clear material. Put rubber mask on the glass of the lights, paint all with silver, with and dark paint before adding the final colour. The idea is to put LEDs behind the lights.

Hint: I added small holes in the box below the vehicle for electrical contact from wheel-sets to the vehicle, but didn’t tested it yet.

I added magnets in the upper frame (5mm x 1,5mm from a usual cigarette paper brand) and small pieces of steel in the roof. I recommend adding magnets at the very end.

Use plastic from blisters or film for the windows, there is a special space inside to glue them from the inside against the frames. BTW: I recently added a measurement of the inner window frames to the images.

I used paper clips and M3 screws to add couplings.

If your centre light breaks, I made a replacement part ... just in case, I know ....

Paint it RAL 2000 yellow orange, roof in tar and lower parts black.

Important Hints?

1) If you use magnets, insert them at the END or you will have special fun with your tools
2) Add side windows AFTER the front windows or you block your access routes
3) Dimensions of the windows are from the cut-outs of the CAD-project, make the window panes smaller and test fit
4) go to hint 1 and 2!

Origin and licensing

The design is based on the boxcar in [1, p. 202] and several photos.

I don't want any commercial use of this design and prints.

You are free to print my work for your projects, close friends and maybe your model railway club. Please post your makes.
