Here is the history of #9, along with some pictures from its past. I will add more historical pictures as photographs become available for me to post here.
SRRR #5 was built in 1891 by the Portland Company of Portland, Maine. Builder's plate number 622, it was the second two-foot gauge engine built by the Portland Company. Sandy River Railroad officials were so impressed by its predecessor, SRRR #4, that they ordered another similar locomotive the very next year. The Sandy River Railroad at the time was a busy railroad, connecting with the narrow gauge railroads Franklin and Megantic (F&M) at Strong and the Phillips and Rangeley (P&R) at Phillips, and meeting the standard gauge Maine Central at Farmington.
#5 performed adequately during its years of service, becoming damaged in several accidents and roundhouse fires. #5 briefly bore the name "N. B. Beal" when it first arrived, in honor of Nathaniel Beal, an officer of the Sandy River for many years.
In 1908, the SRRR merged with the F&M and P&R railroads, thus formalizing a union that had informally happened since their beginning. The locomotive numbers were shuffled, with SRRR #5 becoming SR&RL #6. Business was very good, and the new #6 was kept busy.
However, as the years progressed and larger and larger motive power arrived, the smaller engines started to get shoved aside. The 0-4-4's couldn't compete with the 2-4-4's and the 2-6-2's for tonnage hauling. Business began dropping off as well. Finally, in November of 1924 #6 was sold to the Kennebec Central Railroad, ending almost 35 years of service on the Sandy River system.
On the KCRR, the new arrival was given the #4. Her task on this railroad was hauling the coal from the docks on the Kennebec River in Randolph to the Old Soldier's Home in Togus, a distance of a little over five miles.
Unfortunately the coal contract was awarded to trucks in 1928, and the KCRR could not last long on the meager passenger income. The KCRR shut its doors that year, and the two engines, #3 and #4, lay dormant until 1933, when the railroad was purchased by WW&F owner Frank Winter. Winter's goal was the two operational engines. Both locos were hauled by flatbed truck in mid-winter overland to Wiscasset, the first such move of a flatbed truck in Maine.
#4 was renumbered to #9, and put into service. #9 operated
intermittently over the road until early June, 1933, when she was
sidelined for a broken frame member. Sister #8 derailed on June 15,
1933, closing the railroad. #9 is thought to have operated one more
time, in 1934 from Wiscasset to the Top of the Mountain in Alna to show
prospective buyers the railroad.
