Inside Train Escape

One week ago, Thomas was in that train for selling the sweet corn. But till now he did not return. So, I think he has trapped in that train inside and its surrounding area. I am so fear about him. He is a small boy. I went there to find him, but the train main door has locked automatically. No one is in that train. Now I stuck up in the middle of that train. If anyone please help me to escape from this train as soon as possible
