i can't speak for williamsport (although i have seen some serious rail there from the highways)
but, being a psu alum, there isn't much evidence left of rail service in state college
the former station still stands, just off north atherton st. right before the golf course
but no rails are in sight
here's a note on it from this website
State College - The Bellefonte Central built the brick State College station on North Atherton Street in 1930 to replace a wooden structure a short distance to the east on the Penn State campus. A mixed train from Bellefonte served the station until March 1946. However, occasional passenger specials were operated, including one for President Dwight Eisenhower in 1953. Freight service ended in July 1974 when the BFC abandoned its track to State College. By that time, however, the station had already been leased by local government as a bus terminal, a function that continues today.
there's an industrial spur along 26 on the way into town from the east
other than that, just go to the skellar for a beer!
