It appears as if weekend work has changed. I heard one weekend train referred to as Y-120. It seems like on weekends (either Saturday or Sunday) they run with cars for all customers on the line as far as Ken's Foods in Marlborough and switch Safety Kleen and Kens, then tie the train down for the night at the D'Angelo Drive grade crossing. The next day (either Sunday or Monday), the depart and switch NewCorr in Northborough on their way north with lumber and trash empties. It appears as if during the week they may still do the south customers on one day and north customers the alternate day (but I cannot confirm that).
