Curving to the east in the morning light, BNSF 6636 leads an eastbound Z train past Southside Park's six multi-purpose fields - including soccer, baseball, softball, football, picnic tables and playground - as it leaves historic downtown Kingman behind. The town of Kingman, originally chosen to be named "Middleton" after Conrad Shenfield Middleton, a division engineer for the Atlantic & Pacific who along with others filed for a townsite, gave way to the name Kingman after a settlement in the Bradshaw Mountains had already taken his name. Kingman stems from Lewis Kingman, who succeeded Henry R. Holbrook as Chief Engineer for the A&P in late 1881.
