Steam Train

I've started smoothing piece by piece. adding detail where necessary. Like I don't wanna add in every piece and then have to go back through it all smoothing it so I'll just smooth it as I go along adding piece by piece. Not every piece is gonna be smoothed. it'll only depend on its scale or shape.

I have not combined or grouped my objects. Instead I've parented them under specific objects. I actually don't know if this is industry standard practice but I'm using this technique to help me isolate specific parts of the vehicle to easily navigate around certain parts. If I was to start rigging then I would unparent them and combine necessary objects.
