Swinging Through Sparta. A late running New York, Susquehanna, and Western Railway SU-100 had just crossed over Route 15 as it passed through Sparta, New Jersey on Monday, March 14, 2022. Very obviously former Norfolk Southern SD70M-2 NYSW 4064 leads with a recently applied "S" logo and "SUSQUEHANNA" name on the side. This train would normally come through this area at night.
