From the outset it was apparent that the American Expeditionary Force (AEF) would have to build its own logistical network in France; up to 25,000 tons of material would be arriving every day, and by war’s end over eight million tons had been shipped to the AEF. Port facilities had to be built or improved at Brest, St. Nazaire, Nantes, Bordeaux, Rouen, Rochefort, La Pallice, Bayonne, Le Havre and Marseilles. It was also clear that the French rail system wouldn’t be able to move the AEF and its logistical tail around the country. Among other things, they were very short of locomotives. The necessary solution was to bring American railroad equipment to France.
