I am just going to put it in here...

But I might get hate for this but...I think GNE have more simplier and plainer logos, examples - Coast & County - Country Ranger (Not a bad livery but more simplier) 
And just look at all the S&D's very simple with one Icon/Picture. 

One of the best examples is the coaster how much that had changed. 

However I would say there has been a few more complex ones which I like like Crusader.
