       After a couple relatively quiet years, there are several new prototype locomotive models on the scene. Following its SD50 (shown in Newsbox, June 1986 PM), Electro-Motive has built 172 SD60 units to date for Union Pacific, Burlington Northern, Conrail, Norfolk Southern and Canadian National. UP NO. 6020 is seen here, shortly after delivery to the line at Dolton, III. (former Mopac facilities). UP purchased sixty of the powerful units (Nos. 6000-6059), its first order of new power in six years. Another new face, quite literally, is this GP60 prototype. Number EMD 7 was given rounded corners on the nose and cab (look closely) in an experiment to lessen wind resistance. It was later determined that any savings in fuel were not outweighed by the extra cost of the special features, and the round edges would probably not become a permanent characteristic. When new units are introduced, their prototypes (in this case, meaning the first production models) frequently are tested on a number of railroads. This gives the manufacturer additional information about the performance of the power, and it gives the individual railroads a chance to test the units for possible purchase. Here, an EMD test set is returning to its home base (La Grange, Ill.) after a stint on the Norfolk & Western early in 1986. On the Indiana Harbor Belt at Blue Island, Ill., the set includes (front to back) GP60 EMD 7, SD60 EMD 3, test car ET840, EMD unit No.218 (F45 body with test bed inside), EMD unit NO.462 (F-unit body with test bed), and EMD unit NO.5740 (SD45 body with test bed).The entourage is hauled by two IHB switchers. Note the FRED on the rearward coupler of EMD 7.
