Grinding up the .82 percent to Hermosa Tunnel and the 8014-foot summit of Sherman Hill in late September, 1965, Union Pacific 418 leads a motive power consist that could be assembled on no other road: two SD24’s and three SD24B’s. Few roads snapped up EMD’s turbocharged C-C SD24 when it appeared in 1958, and none but UP went for the cabless booster units. But these were true pioneers, the first of the second generation, high-horsepower diesels, and the forerunners of the herds of SD40s that were to come along a decade later. UP bought all four of EMD’s high-hood demonstrators, 30 of the low-nose cab units and 45 of the cabless B’s. For all their pioneering, they were only adequate engines. UP fiddled with three of them, trying to boost output and reliability. All would be off roster by the early 1980s
