[MOC] [STUD.IO] Type-442 'Cobalt'

Trying to make a steam train with a train motor as a base of motion. With mostly common and cheap parts (I hope)

Nice locomotive ! Quite a while ago I did some test with the same configuration as you have here : large wheels on a train motor. My conclusion was that it runs way too fast and it does not have a lot of torque. Did you make some running test ? Did you got the same issues ? I think that you have way enough space available in the boiler if you wanted to fit a large motor.

Nice 4-4-2 Atlantic locomotive. The blue color gives it a French feel.

I have only put in the Orient Express, but I have no space to test it properly(except that it runs). And yeah, may try to make an alternative motorisation for one L motor and maybe a battery box in it

I can confirm @sebulba56's note - using a train motor, Lego steam driver wheels don't get a lot of torque. I made the mistake of initially equipping the 2-6-0 locomotive in my profile picture with a train motor powering the drivers - it worked, but barely. It now has a PF L motor that's proved much more satisfactory. 

That said, your locomotive is a small Atlantic type - who knows, maybe the train motor will work in your case. My 2-6-0 is 10-wide so I'm sure the locomotive's self weight was a contributing factor to its lackluster performance with the train motor. 

That said, I really like the looks of your model! It reminds me of the LNER 4-4-2 Henry Oakley a little bit, especially with the shape of the firebox.
