You’re a horse. You’ve got caught a few days ago by humans brutally and got “tamed” well, you surrendered until one day.

That day was hard.. you’ve got transported with a train to a different countryside. There you saw other horses being tacked on a huge train with no wheels yet. Neither did the way have a normal road, it was just dirt. As a human also tacked you onto the train, you felt the heavy cold metal on your body. At first it didn’t seem to be that bad until you and 50 other horses had to start pulling the huge heavy train up a hill. It was hard and a few horses even broke down and had to be transported back to the base with mules. But you didn’t give up for a while, until you got fed up by the constant sound of the whip one man was holding and the constant yelling to move on and you cracked.
