Between 1939 and 1945, the war revolutionises British railways as the country has to build new trains, set up secret headquarters, move men, weapons and equipment.

At the start of the 1930s, the German railway was the most successful in the world, but the rise of Nazism and its support for the expansion of automobile power begins to curb this rise.

In 1944, the Allies invade Normandy with one idea in mind: to liberate France from occupation by Hitler's Nazi Germany; the Allies spend years designing vehicles to repair the French railways.

As part of the preparations for the Normandy landings, the Allies bomb the railways around Normandy and organise sabotage operations on railway hubs throughout the country.
