Not to burst your buble, but the Orient Express is one of the most famous name trains in history. Its route ran through parts of Europe and into Asia, and was the famous setting of Agatha Christies murder whodunnit "Murder on the Orient Express". (It is not to my knowledge that she ever road roller coasters, not to mention frequented American amusement parks.)
This is where you should probly begin to search for answers, not with the roller coaster name-sake.
