The '''''Keystone Service''''' is a 195 mile (314 km) [[regional rail|regional]] passenger train service from [[Amtrak]], that operates between the [[Harrisburg Transportation Center]] in [[Harrisburg, Pennsylvania]], and [[30th Street Station]] in [[Philadelphia]], running along the [[Philadelphia to Harrisburg Main Line]] (known as the [[Keystone Corridor]]). Most trains then continue along the [[Northeast Corridor]] (NEC) to [[Pennsylvania Station (New York City)|Penn Station]] in [[New York City]].
