UP DD35A 71
Title:  UP DD35A 71
Description:  Union Pacific Railroad DD35A 71 at Council Bluffs, Iowa on May 31, 1965, Kodachrome by Lou Schmitz, Chuck Zeiler collection. This locomotive was completed in April 1965 (c/n 29985) on EMD Order 7797 and retired August 24, 1981 and scrapped. It produced 5000 hp from 32-cylinders (two 16-cylinder prime movers). When EMD built the DD35, the intention was that it was a B (Booster) unit, no control cab, to be mated to a GP35 for control. The DD35A version with a cab was built in 1965 for the UP (after the DD40 model had been announced) and had the sloping radiators that were applied to the 645-engine SD40 test units. While the DD40 was to have two 645 diesels, the DD35A had two 567D3A diesels. UP 70-83 were built using reconditioned GE 752 traction motors (with 74:18 gear ratio) from trade-in Alco FA and FB cab units. EMD used the designation 752E20A for these reconditioned traction motors. UP 84 was built in part using the reconditioned EMD D67B1 traction motors from wrecked trade-in UP GP9 159 and was equipped with 62:15 gearing. The DD40 design was cancelled in 1966, however, EMD did build 47 DDA40X Centennial locomotives for the UP starting in 1969.
