I was in Medfield this morning and heard B-729 working in the Walpole yard just west of Walpole center. When I went over the tracks on Rte. 27 I could cold see him working in the yard. He was chatting with the MBCR Branch Line dispatcher on Channel 54. Framingham was mentioned in one of the transmissions. I will update this post if I hear who if anyone is working B-729's usual Middleboro Line route.
The FRA supposedly ripped many engines in the area, don't know much more than that yet. I believe B729 might have gathered the Middleboro and Walpole engines to take them to Beacon Park or Framingham to be repaired. I do know that B733 will be doing some extra journeys tonight as well, but I don't know for sure what they will be doing, but if B729 left it's power in Framingham, Walpole or Beacon Park, B733 will probably return everything back to where it came from.
BTW, you sure it was B729 and not B725 or B735? I know B729 worked the Chocolate in Mansfield because B735's power was ripped.
