What role did trains/railways play in the war effort of both sides in WWI?
During WWI Russia used light and heavy armored trains. The light trains contained 76mm guns. Austria-Hungary used armored trains against the Italians. Before the war, Germans invested heavily in trains. Sometimes trains were called " iron horses." Before WWI trained were used by farmers to move their Harvest to a market. One of the problems with these " war trains" was that they tipped over very easily. Trains were sometimes used to bring food and ammunition to the men on the front lines.
