Following CSXT's purchase of Pan Am Systems, CSXT and NS chose Genesee & Wyoming (GWI) to operate Pan Am Southern. GWI, in turn, selected its Pittsburg and Shawmut Railroad (PSR) subsidiary to operate Pan Am Southern. PSR — doing business as Berkshire & Eastern — will operate, maintain, and market the Pan Am Southern freight rail lines previously operated by Pan Am Railways.[2]
Surface Transportation Board approval of the formation and operation of B&E was contingent on the Board's approval of CSXT's purchase of Pan Am Systems.[1] The Board approved the CSXT–Pan Am deal on April 14, 2022.[3] B&E began operating Pan Am Southern on September 1, 2023.[4]
