While out and about in Worcester this evening I spotted SEPO/Q426 Idling away at Greendale with LTEX MP15DC #1524 painted in blue and white, right behind the road power. Per another thread elsewhere on Railroad.net there was a report that WATCO was swapping out power at Rumford, Maine and a unit presumed destined for that purpose had been spotted at Greendale recently, but this is not the same switcher mentioned in that thread. Is WATCO getting another one, or where else could LTEX 1524 be destined?
