Seeing a dog riding the subway alone every day, an inquisitive passenger tracked him.

An Engine Fanatic

After several months of observation of the dog's behavior by metro station employees, they concluded that the dog merely enjoys being near the engine of the train. He runs straight for the seats above the engine every time, and if those seats are already taken, he will definitely seat as near to them as he can. When he is traveling the Metro or underground train, he often sits straight on top of its wheels.

Referring to him for such a significant period as "the traveling dog," the staff members finally realized they should give him a name. It was only reasonable to consider his love of the engine while choosing this one.
