They tend to be "as needed"! Usually,the engine based in East Brunswick(the BIW Hardings Plant on OLD Bath Rd).,will run the 5 miles into the Brunswick Yard(off Stanwood St.) to drop any cars & lift any for/from the Guilford connection around 8-9AM,usually 3 days a week. They usually work as far east as the Maine Yankee Spur. The train based in Rockland will often run west to meet the other crew somewhere long the line & exchange cars. Then,they will return to Rockland,stopping to pick up loaded cements at Dragon plant in Thomaston & run down the Rockland Wharf Branch to switch out the empties & set the loads for transfer to the barge. Your best bet,since your in Waldoboro,iI
think,is to concentrate on the eastern end in Thomaston & Rockland. Hope this helps. Bud
