Galaxy Express 999 S01 E53 Tetsuro, of the Planet of Mirrors

A boy who looks just like Tetsuro, named Manabu, and his brother work hard and are able to purchase a single pass for 999. The brother passes away before they can make it to the town where 999 arrives. When Tetsuro goes out on his own, Maetel mistakes Manabu for him. Tetsuro arrives and fights Manabu, but they quickly become friends as they have so much in common. When Manabu tries to board the 999 however, he is told that the pass is counterfeit.
