Challenger

Challenger (he/it, 212-02-3985, suggested by SGuySMW) is essentially Big Boy Jr. He is the little cousin of Big Boy and the latter's predecessor. He was initially the ideal steam locomotive for carrying heavy freight trains up the mountains, but by World War II, those trains grew longer and heavier. As a result, Big Boy was born. This Challenger, No. 3985, was part of the squad until Big Boy's successful restoration. He now resides in Silvis, Illinois on a former locomotive storage facility. Challenger decided it would be a golden opportunity to follow Big Boy and join The Wiki Camp 2 Jr. Now that he's here... well, we'll see what happens.
