[2] The bankrupt New Haven was included in the newly formed Penn Central Railroad on January 1, 1969, which abandoned the tracks north of Southampton.

Penn Central promptly went bankrupt in what was at the time the largest corporate bankruptcy in U.S. history, and was folded into government created Conrail in 1976, which became the new operator.

[3] The company gained an additional 1.7 miles (2.7 km) of track in Easthampton by a $17,500 purchase from previous owner Boston and Maine Railroad on March 20, 1984.
