In war in 1863, why is it an advantage to have more railroad tracks than your enemy?

When discussing railroads during the Civil War their role is often overlooked. They proved a vital asset in the movement of troops and materiel, ultimately allowing the North to achieve total victory. After fighting broke out in 1861 the country had a rail network totaling more than 30,000 miles.

i think it is On January 1, 1863, Abraham Lincoln issued the final Emancipation Proclamation, which declared that all slaves within the rebellious states “are, and henceforward shall be free.” Bitterly denounced in the South—and by many in the North—the Proclamation reduced the likelihood that the anti-slavery European powers would recognize the Confederacy as an independent nation and opened the way for large numbers of African Americans to join the U.S. armed forces. At the same time, tensions created by losses on the battlefield and sacrifices on both sides of the home front were reflected in public meetings and demonstrations. Though peace movements were increasing in strength in both the South and North, a majority on both sides remained bitterly determined to pursue the war to victory.

Only two months after the North’s major defeat at Chancellorsville, Virginia, in May 1863, the Union victory at Gettysburg (July 1–3, 1863), dramatically raised Northern morale. The fall of Vicksburg, Mississippi, on July 4 militarily split the Confederacy in two—and set Ulysses S. Grant on the path to becoming the Union’s final and most aggressive general-in-chief. In the Confederate states, food shortages and exorbitant prices caused riots in several cities. Rampant guerrilla warfare in Kansas and Missouri created a war within the war.
