Santa Fe had plans for a second locomotive streamlined like the 3460. That was going to be 4-8-4 #3765, the first of that class. The streamlining was canceled during construction because it was found that the streamlining would add too much weight to the locomotive. However, work had progressed far enough that it was equipped with the smooth pilot (instead of the standard boiler tube one) and stainless-steel handrails along the boiler.
