The train conductor stopped the train and saved a dog.
A lot of times, when a homeless dog is discovered on the railroad tracks, the train has to stop so the authorities can take it away. This delays the passengers who are on the train, and they get to their destination late..
Sometimes the result is a sad one; the train keeps going and passengers just feel a bump on the tracks.

A train conductor in Santiago, Chile didn’t want to kill the dog on the tracks. He could have called someone to remove and rescue it, but instead he stopped the train and got off the tracks to save the dog himself.
In the video, you can see the hero man walking up to the scared dog. He calls for the pet to come closer, but when the dog stays put, the man slowly lifts his hand toward the dog, hoping not to get bitten.
Luckily, the dog was friendly with the rescue and the train conductor grabbed it by the scruff of the neck and pulled it to safety. Another train worker took the dog and helped save it.
The driver got back on the train and apologized for the delay, saying he couldn’t run over the dog. Everyone applauded him as a hero!
