That is the sand box.
The DD35's were originally built with the sandboxes in the end of the carbody. This caused havoc with infiltration of sand into the adjacent electrical locker with all the relays and switchgear. I remember seeming a DD35 come in to Laramie one night with fire in the electrical room. A local maintenance guy used a fire extinguisher on it like it was a routine thing.
Because of that problem the UP DD40's were built with sandboxes along the handrails, and some older DD35's were modified like that.
One of the inside jokes about the DD35's was that "DD" stood for "dead and drained". They were getting really tired by the late 1970's. By comparison the DD40's were a great improvement, and they tended to receive priority maintenance because of their use on hotshot trains. They had higher speed gearing like the 8000-class SD40-2's.
Don't correct me with all that "DDA40X" lingo because we just abbreviated it on the job, or called them "69-hundreds".
I have an EMD DDA40X loco service manual I might consider trading for something good ...
