Any job out of Middleboro is nocturnal now. Before the Middleboro CR line rebuild B729 had a midmorning start to Braintree, however is now called after the last MBCR train around 11 PM. You may catch B727, the local to Attleboro, switching and building their train on Alden siding late in the afternoon, but as for MC, as stated previously, they run as needed to Middleboro.
Also of note with all CSX trains now run at night, both MC and FVRT make daytime drops and pickups alone without CSX crews assisting with switching as both had previosuly enjoyed. Not sure how much that adds to either shortlines runs?
