The Gettysburg National Military Park expansion is 45 acres donated along Plum Run in Cumberland Township, the southern end of the battlefield. This is a 1909 photo from Plum Run Valley, with Little Round Top (left) and Big Round Top (right). Confederate troops were unsuccessful in trying to take Little Round Top on July 2, 1863, the second day of the Battle of Gettysburg.

The expansion of Gettysburg National Military Park places Gettysburg/Lincoln Railroad Station on Carlisle Street within the park's boundaries. The Gettysburg Foundation, the park's nonprofit fundraising group, bought the station from Gettysburg Borough for $500,000 in January 2014. President Lincoln arrived here the evening of Nov. 18, 1863, and delivered the Gettysburg Address the next day. The station also served as a hospital during the Battle of Gettysburg. The depot, build in 1858, received a top story addition in 1886, and a
new roof in 1902.

On Dec. 11, 2014, Congress approved expanding Gettysburg National Military Park by 45 acres. The bill was part of the $585 billion National Defense Authorization Act, which passed in the House on Dec. 4, and in the Senate the
next day.

The expanded acreage is land donated in 2009 to the Gettysburg Foundation along Plum Run in Cumberland Township, the southern end of the battlefield where the cavalry skirmished. The Battle of Gettysburg, July 1-3, 1863, pitted Mead's Army of the Potomac and Lee's Army of Northern Virginia. It was the deadliest and considered the most pivotal battle of the Civil War.

Historic Lincoln Train Station on Carlisle Street in Gettysburg will now be within the boundary of the park. The Gettysburg Foundation, the park's nonprofit fundraising group, bought the station from Gettysburg Borough for $500,000 in January 2014. The National Park Service will use the station as a downtown information center.
