Took this time some inspiration from @johndrinkin and his art deco/retrofuturistic trains and some existing trains with smooth "bathtub" cowl appearance.
Here few versions of it with a slight forward and backward cowl and with standard parts and customs wheels that suits better
With custom wheels that are slightly bigger XLL
With standard partlist
Due too similarity of them here some other photos and angels
Hoses job (it was painful and full of struggle but I`ve made it! )
Size comparison between desighn with custom wheels and sandart(sorter)
Been working on this for way too much time but got a few new ideas and some of them use as improvements for PRR GG1 family
Maybe will try to make a "tank version" based on some German/Dutchland streamlined train (if not fall fully insane)
