...that had the Lackawanna heritage unit leading, I did manage to photograph NS 66Z crossing over the Raritan River in Neshanic, NJ. Motive power was NS 3354 (ex-CR 6403; SD40-2), UP 5811 and UP 6693. The river's shallowness indicates how this area has received very little rainfall this month. Not bad for photography but bad if one's livelihood is farming! Regarding that 18N, it would show up much later in the afternoon after being delayed during its eastward trip.
