Apparently, NHVT didn't get track rights down to WRJ to pick up their cars until sometime in 1993, and got a whopping two years out of that until they lost the Berlin route out of Woodsville with the condemning of several bridges. Dave Poor, engineer on that final March run, notes that at the time, there was no local traffic between WRJ and Littleton, and that GTI's trains were sometimes just a single car.
Perhaps these were the cars that went to Commonwealth Lumber in Littleton until 12/97? It seems the salt traffic for Wilson's was already done by then.
