A top down 3D render in Blender of the chassis for my C class locomotive. The body shell has been removed to give an overview of the chassis and mechanism. It's an 0-6-0 wheel configuration with brake lining on the back 4 wheels as prototypical. On top is the motor bracket with the indication of a small coreless motor inside. On the motor is a worm gear that goes down to gears that connect it to the middle drive wheels.
This is a side shot of the same mechanism. The daylight underneath the boiler is more prominent from this angle in which an indication of the valve gear is present.
Top view of the chassis with the motor bracket removed, to show the gear train going down to the drive axle.
I've decided to rebuild the chassis and mechanism for my #3Dprintable C class locomotive (AGAIN) to use a different motor. Making this the THIRD motor change. However this motor has a lower RPM so I can shrink the gear box and drive it from the middle set of wheels. #modelrailway #3Ddesign #Blender
