Killer sound as the engineer of the yard job cranks open the 710 in the SD70MACe that will lead M202 later that night in Taft, FL. A few minutes of high and low idling before he notches up. Then they pull the power to the wye.
They’re designed for that, watch some load test videos, locomotives get left in notch 8 for quite some time, when under load they can be left in notch 8 basically until they run out of fuel
You ain’t got the full experience until your under a overpass with a 70 series and the hogger is shoving a long string of cars into a yard with a AC4400CW and a ES40DC behind that 70 series. The 710 will drown out the GE’s.
