BNSF 3GS21B 1236, Saginaw, TX 11-01-2008

One of three-unit Genset power consist bringing transfer cut up ex-FW&D to ex-ATSF, sitting on transfer track. These things sound like several diesel generators running- kinda remind me of emergency generators. Don't sound anything like a 567, 645, or 710 of an EMD or an FDL from GE.
