Theories
Many fans have speculated that Champ is Porter, due to their nearly identical appearances and Champ's interest in trains. Champ also does not appear in any of the same games Porter does, and vice versa. This was disproven in the Wii U app Animal Crossing Plaza, which reveals that Porter's birthday is April 17th, whereas Champ's birthday was June 4th.

It could also be possible that Champ is Porter's brother. This is supported by the fact that when entering the town for the first time, it is possible to see both the engineer and Porter at the same time, who both share the same model. Another fact that supports this is with Porter's e-reader card description, which states that Porter and his brother are rumored to occasionally switch places engineering the train.
