After my analysis I think the Correct scale of the transport is more 120M than the official 90M. My privious mock-up was more like 90m transport, so I made another mock-up (below) refining things a little, while I was preparing the photoshop file for you guys.
I've included a scale chart of the correct 120 m length transport into the file.
I'm having some difficulties uploading it with yousendit, any ideas how to share à 300Mb file easy, quick and free?
