Rex [APT- 01]

This takes place, in the future, where protogens and humans coexist despite some tension between them... A compagny, one day, decided to create protogens... who are entire trains ! They control everything in the train and have infinite battery (don't ask how). They also are called proto-trains or APT ; Automatic Protogen Trains. Rex is one of the first proto-trains created ; he's cheerful, funny and full of joy towards his passengers. He just doesn't like those who put a mess on his train, or sneak in without paying their ticket, or just straight up insult him.
