The article mentions that it was the Southwest Chief (#3) and it had two engines. Likely it needed both to provide HEP and sufficient horsepower to travel the route (Esp. Raton Pass).
We hope you are not assuming HEP can come from 2 locos ? It isn't so/. Only one loco provides HEP even on the long auto trains. Only Via has a set up where 2 locos provide HEP to alternate cars. Now with the Chief maybe having more cars for the scouts the HEP might have to be shut off to provide more power to traction motors on the HP loco.
Sorry, I just saw this now.
No, I'm aware that only one engine supplies the HEP. However the engine providing maximum HEP is only able to supply 2,525 HP to the rail. If one engine fails, 2,525 HP may not be enough to make track speed (Chief is authorized 90 mph) and/or get it over Raton and Glorieta. So they waited for a freight motor to give them additional horsepower.
And who is this "
we?" Is there an organization you purport to represent?
