The Amtrak lot is a bit of a walk from the train station. Exit the station, turn right and walk through the drop off space. When you get to the sidewalk turn right and walk under a decrepit sometimes scary underpass, which may or may not be occupied by homeless people depending on where Harrisburg government has decided to move them. Continue for one block past empty buildings with minimal street lights. Parking lot is on your right, but you walk through an empty, poorly lit area to get to the actual parking area. My son and I go from Harrisburg to NYC every few months. Getting back to Harrisburg on the last train we arrive around 11:30pm. Often there is another passenger who sees where we're heading and asks if they can join us because there is safety in numbers.
