A Pan Am Railway OCS kicks up the dust at a dirt road crossing as it rolls EB on the old B&M at MP 451.81, Hunt Road. The classic searchlight signal still retains the numbering scheme of the old B&M mileposts, showing a location of 171.9 miles from Boston. Guilford introduced a new mileage system for the consolidated MEC-BM-DH, starting at MP 0 in Mattawamkeag, ME.
