KonstalN.zip

sended as requested.

The 150N has some duplicate variable/shape names, and the syntax is messed up in both.
I have already fixed these issues, but it should be mentioned that I made changes to your code structure of the model files.
(still working on adding them in).
//EDIT: almost forgot, I will still need icons for them. (for the items).
//EDIT 2: they were also upside down. fixed that too.

looks like theres some model issues with the Konstal Na.

Also, they aren't quite center and a little wide, this is minor to the point I don't really care, but I thought it would be worth mentioning to you.

Here you are. New Models but in OBJ. I guess its good.

I can't render trains and rollingstock with obj, unless you want this to wait till the rewrite.
The port's render will only take .java.
