Farmland and railroads tracks each contribute to a side's advantage in a war by providing the group with more supplies and food for them in the war. Railroad tracks helped contribute an advantage in a war by making it easier to transport many things to the battle field, and trains could carry many tons which allows people to get A LOT of supplies for the war. A train could carry things like food, gear, armor, artillery, and etc. This gives a huge advantage to one side because they can get supplied easily without making it a big hassle. Farmland helped contribute to an advantage on one side of a war because it was an easy way to grow food for the soldiers. Farmlands could produce a lot of food, especially when you have a lot of land, and can be given to the soldiers to keep them from starving. Farmlands was one of the ways a group of people used in wars to produce food and not worry about not having enough food to feed to the soldiers.
If you remember newspapers were how many people envied war and how many thought that the British soldiers did wrong in the Boston Massacre where both sides were at fault.
