SJ Da 939

[LEGO Train 12 Volts]

Dear train fans,

it's time for holidays and for a new step in my European Tour 

...time to visit Sweden...

...with the SJ Da 939!

I found on the net two models built in Lego (by Selander Da Locomotive and Haddock51 Dm3 Locomotive) but none with the cam transmission system

 

thanks to zephyr1934  for his custom pistons that made this model possible!

As always the model has a switch with different positions, to turn the motor on and turn the motor on with lights

Now a little show:

See you next month for the last episode of the European tour!

Lovely rendition of this awesome veteran!

What a brilliantly conceived SNOT-work for the locomotive body! The pantographs are also very clever.

Thanks Tenderlok, the pantographs are nice but extremely expensive and fragile ... going back I think I would design them differently!

Your welcome ... So Im examining your running gear photo ... Does the motor turn the essentric to move the rods which turn the wheels or am I missing a gear connected to one of the wheels?

Yes it's correct: the motor turn only the cam and the rods transfer the motion ...no gear is connected to the wheels!

Very awesome how it its speed/traction using this method

Amazing build.  

Does it run smoothly in standard curved track?

Oh yes, it run very smooth due to the powerful reduction ratio

Perfect assembly of a complex form. It was very similar. And worthy technical solutions. I want to note that all your work is educational, not only in terms of the art of lego modeling, but also acquaintance of those interested in the railway park of the whole world. It remains only to quietly dream, when your gaze may fall on the railway park a little east of Europe. On a country with exceptionally long railways ...

Well said @Nemo57. A beautiful model which captures the shapes of the original well, and a good one for the penultimate model of this interesting project. I only wonder if yellow trans-clear "lenses" might work better for the headlights; they'd give a warmer glow than the cool white, better matching the reference image. Otherwise a great work, as we've come to expect!

Sorry I had not seen the question ... the speed is lower than the standard lego train set, but the pulling force is higher

I know what you mean but I don't know much about those areas and I struggle to find an iconic model

Thanks for the good advice!

Well, I think you can always find something cult and interesting in any country.

No doubt about that ...but WOW this is insane!

Very nice model and very interesting cam mechanism, compliments to you for having implemented it.

As regard that east european country nemo57 refers to I have three iconic models for you  :
