Flash- Here is a photo showing what came from the SD45. The end of the shell is also from the 45. Hope this helps! Thanks ya'll!
Thanks Hemi - You know this is something I usually notice several days after I "finish" something. I will go back and do this. Good idea!
Flared radiators similar to SD45 style, enhance cooling of charge air for better dual fuel performance. the one on the RLM units where just normal sd40-2 radiators but just flared. where the sd45 actually had a different design/look to them (the 3 section screens vs. the 2 from the sd40-2) I hope that is understandable. the shop that built those locos actually is here in tacoma, wa.
