I was able to find this pair (6-84078), and decided to pick them up since Burlington Northern is my favorite Railroad next to Santa Fe. After I opened them up and did a quick inspection I noticed that the two A units are actually based off two different E8 prototypes.
9935 is the lead unit and has a beacon and a singular headlight. 9940 is the rear unit, has no beacon, but a headlight and Mars light. I decided to research this, and this is actually accurate to those specific road numbers.
Kudos to Lionel for this, since not only do these have road name specific details, they also have road number specific details. I thought this was pretty neat and wanted to share my findings.
