Seeing a dog riding the subway alone every day, an inquisitive passenger tracked him.
Boarding and Disembarking
The dog's simple ability to board and leave the trains caught most observers off guard. For some users, using public transit can cause stress. Nevertheless, the dog appeared to be completely apathetic as it went from one train to the next finding a seat and comfortably sitting in. The throng or the loud noise in the metro station seemed not to disturb him. Even so, he could glance out the window and enjoy the scene as he passed by. Looking at him made it very evident that he knew exactly what he was aiming for.
According to a photographer who spent a day watching the dog, he waits at the nearby benches until he feels the vibrations of the incoming train. He then approaches the edge of the tracks, conscious of the exact door location all the time. Most of the guests let him in first.
