Rock Island Locomotive Portfolio 1950-1980 from Morning Sun Books is a colorful look at the RI's unique diesel roster. From the unorthodox purchases of 44-tonners from Davenport and Whitcomb rather than then-standard General Electric, to the late Alco-era C415 switcher model and EMD (and EMC) TA and AB models, to the standard E7 and E8 designs the Rock liked to sample the offerings of many builders. Alco cab and booster units, re-engined by EMD, oddball Lima 800 HP LS800 models, and other abnormalities made The Rock a railfan's paradise in the 1960s and 1970s. Running on a shoestring budget in later years, the Rock Island acquired used locomotives from many sources, often through local supplier Precision National Corporation and suitor Union Pacific RR. In Rock Island Locomotive Portfolio 1950-1980, diesel fans will enjoy exploring the roster of this railfan legend with diesel authority Steve Timko. Softcover, 96 pages.
