Lately I have noticed there has been a regular UP empty cars movement from Bacchus Marsh. It tends to run most, if not all weekdays during the early afternoon as an N class loco hauling a 6 car H set. Today for instance it was seen through Rockbank at about 1340.
What I'm wandering is, why? As far as I knew all Loco hauled sets that stable overnight at Bacchus Marsh leave in the AM peak, stable at Spencer St, then return in the PM peak and stable overnight, so what is this set doing down in Bacchus Marsh during the middle of the workday?
By the way I don't know for certain that Bacchus Marsh is where the train is coming from, but I can't see it being anywhere else on that line.
Any info would be great.
