I think he may be confusing the GP60 with its little sister, the GP59. The GP59 did have a 12-710, and can be hard to tell the difference between the two at first glance, since they share the same frame and are nearly identical at first glance. If you want the sound of a 12-710, then download mikey186's 'EMD F59PH & F59PHI Engine Sound', <KUID:274806:4806>. The F59 is equipped with a 12-710. Then again, it was easy to tell Norfolk Southern GP59 #4610 from GP60's when she was a heritage unit before being painted in NS colors. I'm just wondering how different she'll look after being rebuilt into a GP59E at the Juniata Shops.
