Also, the World Conventions/Fairs of Industry/Inventions, Crystal Palace and all that good stuff?
It's in Normandy. It's ALL in Normandy. AFAIK there were no "Modern" World Fairs. I did 2 of them during the IT, planned another one when the BT rolled in, and I'd assume they would keep going for some time before they are ignored, what with their Orient Express extravaganza and all.
Also: Orient Express is much more than Paris to Constantinople. With great investment and ingenuity, Normans coordinated rail networks of several nations and companies, eventually developing a network stretching from Oporto to Constantinople, Moscow to Rouen, all with the Flemish Standard Gauge. There was also a offer to build a Swedish version of Cape to Cairo, but I don't know how that went.
