After visiting the United States in 1869, Georges Negelmackers, the son of a wealthy banker, dreamed of building the railroad in the European countries to provide the people benefits of traveling in a luxurious mode of transportation. Only rich people were able to travel in luxurious trains. Europe was made up of different empires and kingdoms and the emperors and kings were not jealous protectors of their railroad systems.
Because the European kings were related to one another, it made it easier for them to utilize their relationship to get many things done. King Leopold II used his relationship to make it possible for Negelmackers to get his railroad work started because the king has interest in trains. King Leopold II was offered free train travel if he helped Negelmackers get his contract to build railroads. King Leopold was not the only king who enjoyed traveling in train carriages, King Boris of Bulgaria and King Carol II of Romania liked it too.
Traveling in the Orient Express was adventurous. The train transported people from London to the heart of Cairo crossing through many cities. Soon it became a place for authors to write novels, one of those authors is Graham Greene.
