A little Friday fun-- how many differences can you count between these two units? Same parent company, same loco type (after rebuild), on the same railroad. I count at least 15. The CCKY has arrived at the Georgia Pacific run around to retrieve inbounds left by NS local AC01. To expedite the move, 2171 was on the rear of the outbound cars. 2179 led, and headed into the siding onto the pickup. 2171 shoved outbounds for NS down the CofG main. Secure the cut, combine the power, and off they go. Works great provided both crewmembers are engineer qualified, which they usually are.
