Own construction of a mine locomotive

For me, a more realistic sound belongs to a realistic model.
That's why I made and edited sound recordings from the original.
The preliminary result I have loaded decoder in the DCC and even made a video to the sample.

My god there's no one driving!!!
I am one (of the few) that enjoy the sounds.

Nice! I too like sound in my models -- it really brings them to life.

It has meanwhile passed a lot of time and so I have once again made my BBA.

Linear servo for driving the brake lever

Yes, I have finally managed after many failed attempts to move the hand brake lever with a linear servo.

But that's not all the locomotive's arm moves with what you can see here.

Luckily, there is nothing you can't do better and so I decided to make further improvements to my BBA.

But see for yourself:

Due to various conversions and attempts, the original base plate was very perforated and did not allow any further improvements. So I completely renewed the base plate and built 3 pieces as a precaution.  Of course, there are also additional new boreholes. With my BBA, the space is unfortunately very limited and I would like to accommodate a capacitor for the decoder in the cavity of the travel switch.

Over this core I bent the sheets for the travel switch fairing.

Volker Gerisch had supported me with the travel switch itself and we had several of them cast by 3D printing. The key with which the direction of travel is also switched in the original is milled out of stainless steel and has a 0.3 mm bore at the end.

This is the pressing or embossing tool with which I shaped the seat shell.

With this tool I have a cross slot, milled into the lower end of the standpipe of the seat shell.

Here are the individual parts for the seat. Consist of seat shell, standpipe, the reinforcements that come together in the cross slot from the standpipe, the foot plate and a reinforcement ring.

After soldering the standpipe, I drilled through the pipe to be able to guide a wire core.

The seat shell was soldered to the standpipe and the reinforcement ring.

The foot plates from the seat were each fastened to the base plate with 2 X M0.6 mm screws with nuts.

The first locomotive driver has already arrived and so it can continue.

Helmut, Your ongoing efforts to revise and improve your work are exemplary.
The results are terrific.


I am reeling in stunned disbelief. Satisfactory. -- Russ


Well done, Helmut. Clean work, nice parts.




great to see the controller parts found useful. Are you going to have them moving according to speed and running direction?

I'll make it. If I have to fly the five feet like a birdie.
I'll fly it. I'll make it.
