New polycount and remodelled tube train

Some screen shots of the final tube train and tunnel. It's been

remodelled due to file size and upload requirements. Yet to be animated etc, 

and the final result is quite delicate and skeletal! I'm going to put some tube lines (in blue) 

here and there going down into the abyss below. I like the idea that somehow 

we are able to see things we wouldn't normally be able to see e.g through the tube train 

walls to the platform and through the floor to the abyss below.

 Halved the polycount to approx 400k, by remodelling. 

Final tube train, tunnel and platform. Next step to create an equirectangular skybox with tube tunnels disappearing into the abyss. I'll attempt to do this by creating all of them in situ, then taking a 360 screen shot and reimporting it in as a new skydome. This will keep the polycount and draw call low too.
