Hi Taliesin898
First Welcome to the NG Discussion group, you can find a lot of information on this website, now to answer your question.
I did find some information, on the Railroad in the books called Railroads of Vermont by Robert C. Jones
All the Three Foot Locomotives were built by Dansforth -Cook Locomotive works of Patterson, New Jersey
# 2 Built by Dansforth Yr ?? a 2-6-0 known as Londonderry
# 3 Built by Dansforth in 1881 as a 2-4-0 the engine was converted to a 4-4-0 and Renumbered tp 193 in 1892, and sold for scrap in 1901
The Locomotive carried the Name J.L.Martin
# 101 Built By Dansforth in 1879 as a 2-6-0 the engine carried the Name Battleboro, scrapped 1906
All information came from the said books, also if you are looking for more photos I would suggest you pickup all Three Books, Railroads of Vermort, Vol # 1 &2 plus the pictorical. I hope this is of some help to you, Pat
