Knockout is sorta like the leader of the crew, and he's also the kinder and wiser one of the other engines. And when another engine needs help on the hill, he goes up and acts like a banker. And is also a hard worker and gets his job done in lickety-split and sometimes, this makes the other engines jealous.
Knockout is EMD SD40-2 diesel locomotive colored yellow. With his windshield windows acting like his eyes, while his wipers act like his eyebrows.
