I've been looking for research resources for a roster of the 3-foot gauge Worcester & Shrewsbury RR in Massachusetts. Apparently they started operation in 1874 with steam "dummy" locomotives. I have only been able to find later blurry photos of #4 0-4-4t and #5, a 2-4-4t or 0-4-4-t locomotive. Literature states that the line was converted to a standard-gauge troley line in 1900.
