After the NBSR westbound freight departs for Maine, the station in McAdam becomes quiet yet again. Tourists make their way to visit and walk around to view this amazing structure. There's a local freight just departing St Stephen, heading north, but they're a few hours away. During the summer months, you can stop in to the station on Sunday's between 1-4pm for some "Railway Pie", which I've heard is tasty, but haven't had the chance to make it up for.
