UP U25B 625
Title:  UP U25B 625
Description:  UP U25B 625 at Denver, Colorado on August 26, 1965, Kodachrome by Chuck Zeiler. Number 625 was built in August 1961 (c/n 34224), retired in September 1972, sold to Morrison Knudsen becoming MK 11, scrapped by M-K in October 1981. It is an early production U25B, one of 11 units delivered to the UP with high short hoods and vertical stairs (road #'s 625-632 and 634-636). The original GE U25B demonstrators were picked up by the Frisco, becoming SLSF 753-756. The steps and narrow walkway around the ends were unacceptable to the railroad, so GE redesigned the U25B and introduced their version of the low short hood. The second four demonstrators, GE 2501-2504 were sold to the UP, becoming UP 633-836. Only 633 (ex-GE 2501) was equipped with a low short hood. Later, in August 1962, the UP acquired four more U25B's with low short hoods (#'s 637-640), for a total of 16 U25B's on UP's roster, out of 478 total turned out by GE. In this photo the trailing unit is steam generator-equipped UP GP30B 738B.

UP U25B 626
Title:  UP U25B 626
Description:  UP U25B 626 and GP30 852 at Denver, Colorado on August 26, 1965, Kodachrome by Chuck Zeiler. The GP30 was introduced as the GP22, but when GE announced the U25B, GM's Marketing Department decided to one-up GE and changed the model designation to GP30. It was decided that the GP30 had 30 improvements over the GP20, the most significant was the central air intake, doing away with carbody louvers and slightly pressurizing the long hood to keep the dirt out.
