Birthmarks of LaGrange: While the railroads of New England, particularly Guilford Rail System, enter a whirlwind of change somethings remain true to tradition. An example being the GP7s and 9s operating in Central Maine. Spotted with the birthmarks of LaGrange, Guilford GP9 12 sits at the Madison Paper Mill in Madison, Maine - keeping the tradition of branchline railroading alive in the summer of 2008.
