Nose to Nose?
Union Pacific was the only railroad to purchase GP30 booster units from EMD. Examples of both A and B are pictured 'nose to nose' (front to front?) in Provo, Utah on Jan. 30, 1977. UP 727 was built in March 1963 and retired March 1984 while UP 729B was built in June 1963 and retired in Sept. 1983. The Rio Grande kept their GP30s active more than a decade longer than UP, many lasting into the UP-SP merger.
