Parallel lines.
Real life example of parallel lines are railroad tracks and rows in a garden. Also the lines on a basketball court are parallel
Tear up railroads (distort supply lines)

Well, railroads helped and also steel! Later cars helped too!

For major trunk lines, where there was competition, the railroads charged lower rates and even gave rebates. For spur lines, where there was a monopoly, the railroad charged higher rates for the same type
Some of the main north-south railroad lines in the United States include the Illinois Central Railroad, the Louisville and Nashville Railroad, and the Seaboard Air Line Railroad. These railroads primarily ran vertically, connecting northern states to southern states.
Railroads were very important during the USA Civil War, because they delivered soldiers, weapons and supplies to the battle, faster than ever before. The railroads also carried big mortars (on flat carts) which fired large shells at enemy battle lines. The Civil War might be called the first railroad war.
no one "took over" the railroads at that time. Although there was railroad regulation, railroads remained mainly in the hands of private enterprise. There were many railroad lines till sometime in the middle of the 20th century. ie: Atchinson, Topeka, and Santa Fe, Union Pacific, New York Central, etc.
A terminal railroad (TRRA in St. Louis, Belt Railway and Elgin, Joliet and Eastern near Chicago for example) is a short railroad, usually in an urban area, usually owned by several other mainline railroads, that connects several lines. A railroad that has cars to be transferred to another line will hand them off to the terminal railroad, which will switch them to the receiving line. An example would be if the Norfolk Southern had a car to go to the Wisconsin Central. It might give it to the BRC to run up to the WC. This kind of operation has decreased in recient years as more lines have merged and made direct connections between lines.
The great number of private railroad companies in the 19th and early 20th century, who saw connecting lines simply as a form of 'aiding' competitors and not in their own interests.
The early railroads established "polelines" to carry telegraph wires and electricity alongside the railroad tracks. These looked like what are called telephone poles today, but could have large "crossarms" at the top to carry many wires. These began with just 2 or 4 wires for telegrph use, which later had 2 wires for electricity added. As technology advanced, more wires were added to control trains and send other messages along the lines.
