The four-axle locomotives joined Norfolk Southern’s roster in November 1989 assigned to the 3500-numbering series. Equipped with 3,200 hp, the locomotives spent much of their early years in intermodal, freight, and coal service. In their latter years, the locomotives were most commonly seen in local and work train service.
A total of 49 locomotives were built in its class, of which NS purchased 45 units. In October 2013, the locomotives were renumbered to the 500 series to accommodate for the acquisition of leased SD40-2s. Most B32-8’s were retired by NS in late 2015.
In 2014, NS donated GE B32-8 No. 3563 to the Lake Shore Railway Historical Society in North East, Pa.
