Eastbound SEPW-X stretches 'em out across the top of Charlton hill at 10:35. This is the highest point reached on the east end of the old B&A, at an elevation of about 950 ft. and 57 miles west of Boston. At this point in time, ConRail had just cut in single track between CP 48/Jamesville and CP 57/Charlton, which is just beyond the overpass seen in the distance. The train is running on the old track 1/westbound main, which will be removed and the single iron shifted to the old track 2. The reason why should be obvious, when one notices that track 1 has jointed stick rail, and track two has CWR. The reason for this seeming anomoly is that at CP 57, the switch is set up so that track 1 is the "straight iron". A short time after this, a transition was made from track 1 to track 2 on the curve in the distance.
