There is also the Wiscasset, Waterville and Farmington located outside of Wiscasset, Maine.
My son and I just returned from visiting the WW&F and the Portland operations. Here is a picture of the WW&F train on Memorial Day. It is a former 30" plantation engine from Louisiana. The Edaville rebuilt it to 2 foot some years ago. The coach is original to the line, when it was known as the Wiscasset and Quebec. The caboose is a replica built from original plans.
Feel free to email me with any questions or if you would like to see additional pictures.
