Default Es44ac Question

hey dtg i was wondering something how did you update the default UP sd40 few years ago? and could that same method be applyed to default es44ac today?

 

I think DTG is trying to distance themselves from the classic asset packs, so this will probably never happen. Most people will use the Sherman Hill ES44AC anyway.

 

ya now i think about it i don't think they can cause there bnsf es44ac in the pack so.
