In the video, a young boy is seen playing with a toy train set. He is standing at a wooden table with a curved track on it. The boy is holding a blue train engine and is placing it on the track. He then picks up a yellow train car and places it behind the engine. The boy continues to add more train cars to the track, including a purple one. He carefully positions each car on the track, making sure they are lined up correctly. The boy seems to be enjoying himself as he plays with the toy train set.
