The Wiscasset, Waterville, and Farmington Railroad is growing, and currently only has 2 steam locomotives--only one running.  Number 9 is being restored, and they're working on getting number 11 built.

The railroad is doing well, growing, and adding another yard, with a turntable and a roundhouse on the agenda.  Also, both its locos are the smaller 0-4-4 Forneys; the one running is very small.  Adding a "big" 2-4-4 will give the ability to handle longer trains.
