| Delaware & Hudson RS3u 505, Bellwood, Illinois, February 25, 1976, photo by J. H. Nixon, Chuck Zeiler collection. The exhaust stack is sealed with tape, I would suppose this locomotive is pictured on its way back to the D&H after rebuilding at Morrison-Knudsen in Boise, Idaho. In late 1975, the D&H shipped 10 RS3's to M-K for rebuilding to M-K's TE 56-4A specifications, becoming RS3u's. Only eight RS3u's returned to the D&H (numbered 501-508), likely the other two units were used for parts. The orientation of the unit was reversed, and the short hood was chopped and became the front end. This particular unit was originally D&H RS3 4122 (c/n 80524), built August 1953. The major modification was the replacement of the Alco Model 12-cylinder 244D prime mover rated at 1600 hp with the 12-cylinder Model 251C rated at 2000 hp. The box on top of the hood behind the cab became the dynamic brake blower and resistors, re-located from the short hood. The long hood was raised six and a half inches to make room for the larger prime mover. Cooling, electrical, and control systems were all upgraded. This locomotive was scrapped in 1988. |
