NHN runs an average of two trains approximately five days a week: one southbound, and one northbound. The trains generally arrive at the pit in Ossipee around 11:00 AM and depart for the Pan Am interchange around 2:00 PM. "Shuttle" trains are run as needed to bring sand and gravel to the facility in Rochester. Once the train arrives in Dover, it assumes the Pan Am symbol DOBO (Dover to Boston) for the run to Boston. It returns as BODO (Boston to Dover) in the early morning. Until recently when they were replaced with a pair of EMD GP38-2s, the trains ran with several EMD GP9s.
