Vol. 34 #1 is entirely on Boston's Union Freight RR, with good photos of urban street operation from the 1890s to the 1960s. I can't remember seeing any of the photos printed elsewhere.
"Critter" fans will like the 4-wheel geared/rod-driven steam dummies used from 1873 till the 1920s. The enclosed 3-truck Climaxes that replaced them may horrify some of you western logging modelers....
