I guess there’s this system called Positive Train Control that’s federally required on locomotives except for heritage locos such as 4014. The diesels have these. However as of 2024 that system was fully installed on 4014 so she no longer needs a diesel assisting her. The diesel was not on this train and I’m guessing this is the reason why.
DOPE! those take a few hour's to prep. interesting to watch.
Fantastic a Unionised Pacific
