There are a number of web based resources that we use ourselves for either background information on Maine at the time of the Two Footers or about currently preserved equipment. These are listed below in no particular order.
The photos and files sections of both the MaineOn2 and the Maine Two Footers Yahoo! Groups. Well worth a browse for those viewers who are members (why not join if you are not? Links are in the sidebar on the right). The various goodies available include a list of all the Sandy River Freight Cars with dimensions and features and many detailed photographs of currently preserved items plus some historical ones.
The Penobscot Marine Museum has a huge collection of photographs available online, including the Eastern Postcard Companies archive. There are a small number of Maine Two Foot Railway pictures in the collection but many of town scenes, buildings and events and other items which provide an invaluable background for the Maine Two Foot modeller;- http://penobscotmarinemuseum.org/photography/
