The E8 and E9 diesel locomotives share the similar "bulldog nose" carbody style as the shorter, more popular F7 and were powered by two separate 12-cylinder prime movers (i.e., diesel engines) capable of producing 2250/2400 hp. E8 and E9 locomotives also rode on A-1-A trucks (powered axle-idler axle-powered axle), resulting in an exceptionally smooth ride favored by crews. The E8 and E9 were produced in both A-units and cabless B-units; the A-units were usually built to railroad specification of either single or dual headlight and freight or passenger pilot. Like the F3 and F7 of the same time period, the E8 and E9 were utilized in both passenger and freight service.

The "City of Los Angeles" was one of the Union Pacific's "City of" trains, and a direct competitor to trains such as the California Zephyr and Santa Fe Super Chief. With many railroads in the 1950's vying for the attention of the travelling public, the Union Pacific spend 10 million dollars in 1954 to upgrade its passenger services, promoting its commitment to high quality passenger service as well as creating one of the most iconic trains of the golden age of american railroading.

One of the most iconic images of this train were its dome cars ("Domeliners"), which, like the California Zephyr, granted its passengers with an unparalleled view of the countryside as the train would make its trips between Chicago and Los Angeles.

The Kato EMD E8 and E9 locomotive both come in A and B (cabless) variations, similar to that of their smaller F unit sister locomotives.
