Altoona is a city the railroad built. In the mid-1800s, passenger and rail freight had a tough time traversing Pennsylvania’s mountainous middle. A connection from Philadelphia and Harrisburg to Pittsburgh was vital, but the Allegheny Mountains stood in the way. The Pennsylvania Railroad moved into the area in 1849 to begin working on the Horseshoe Curve (2400 Veterans Memorial Hwy); a semi-circular stretch of track riding on a manmade traverse of land between two mountains, which allowed safe and affordable travel across the state.
