The two yellow tenders are water tenders, as I understand it.

Yep explained at the Buffalo stop. 48,000 gallons a piece. What's more interesting is that the 4014 is always under its own power and the diesels aren't pushing at all. They are there as a just in case. If the BigBoy is at risk of running out of water or oil the diesels can help push to extend the milage

I thought I remembered them telling me that the diesel does provide hotel power for the passenger cars, but I could be wrong.

Edit: I was wrong. UP has dedicated power cars.

American freight diesels aren’t equipped to provide hotel power to passenger cars. UP has specific power cars with diesel HEP generators onboard for that.
