I saw a BNSF GP50 #3186 & GP38-2, (didn't get the engine #), on a local switching a lumber mill in Bingen, WA today.

As the 3186 went by, the engine model on the frame was stenciled as GP25-2. Has it been de-rated from 3500 HP to 2500 HP and is now considered a GP25-2?

ThIS BNSF roster lists the series as GP50/GP25-2 but no notes. is a participant in the Amazon Services LLC Associates Program, an affiliate advertising program designed to provide a means for sites to earn advertising fees by advertising and linking to - An online railroad bookstore featuring a curated selection of new and used railroad books.
