I, too, will be purchasing this book. A while back I have hiked the old route, because I lived in the area for 7 years, and I was just starting to research local railroad history.
Along with the old towpaths, and the Middlesex Canal Route. A few years ago, I was in the printing occupation and I was reprinting a brochure for the
Middlesex Canal. 2 pictures in the brochure were in my neighborhood, in Wilmington.
I recently viewed a video on YouTube of the crew moving the RDC unit from Guilford's property in Billerica MA to the Friends of the B&B in Bedford.
