CUSTOM EQUIPMENT BUILDS FIRST HIGH-VOLTAGE ELECTRIC RAILROAD

Morrison-Knudsen Co., Inc. (M-K), Boise, parent firm of the San Francisco-based IECO, built the $52.5-million turnkey railroad for a group headed by the Salt River Project (SRP), a Phoenix utility. M-K used a host of custom-built equipment to place almost a mile of concrete ties on an average day, and it glued together 1,440-ft strings of continuously welded rail with epoxy. Two steps forward. IECO project director J.F. Pearce says that "no one had gone to 50 kv before because the technology was not sufficiently developed to produce locomotives with 50-kv primary equipment." IECO worked with General Electric Co. on them. Another innovation says project design engineer James Lackey, was positioning a lightning shield wire directly over the catenary wire to get low line impedance.
