The cockpit is now done. It has 2 little men in it, and it's covered by a clear plastic dome. The inside will eventually be black and the people wont be very detailed, so that it doesn't distract from the train it self, the main element.
This is where I've fixed big blobs of body filler, which I then shaped and smoothen them.
The aluminum rods and the white plastic bits, I used as some kind of frame to start building with body filler on top. That way I also had the rods as reference to make sure I have the general shape "under control" and knew where to carve away and keep the piece symmetric.
