Actually, there was no diamond - the NAB crossed OVER the Stony Brook on a bridge.
To see for yourself...
Park in the back left corner of the large St. Catherine's parking lot. There you will find a trail into the woods. This trail is the NAB ROW. Walk 100 yards or so and you will come to the abutments, etc.
There was also a trolley line that ran through there, and the bridge spanned both ROWs. You will see this when you get back there. Power lines (that post-date the trolley's abandonment) mark the ROW.
If you cross the Stony Brook and hike another few hundred yards south on the NAB ROW, you will come across a rather large stone arch bridge. Built without mortise, concrete, etc., I understand that it is the largest of its type in the area.
The trail and stone bridge is part of a plot of public conservation land in Westford. Obviously, you have to trespass when crossing the Stony Brook. I'm not sure of the ownership of the small portion between St. Catherine's and the Stony Brook (although it is a well-used trail.)
