Duncan the Yellow narrow gauge engine was chuffing north as he was bouncing around his wheels As he was carrying his passengers heading outside the tunnel, he was bouncing around knowing that he was rocking and rolling around the tracks, Filled with his admiration and was unaware, Duncan had derail when he reached the damaged track that Rusty had warned him about just before reaching the first station.

As soon as Rusty arrived, the workmen, with the help of the passengers (who were not pleased about doing so), work hard to lever Duncan back onto the rails, and Duncan had finished his journey without any further mishaps

During that evening when he was apologizing to Rusty and reconcile their friendship, both of them had saw as you were arriving to the shed knowing You had a long day of pulling coaches and shunting freight cars, Duncan smiled as you were back, "It seems that you're back from carrying passengers I've heard, Well you know I was rocking and rolling on the tracks and ended up in the tunnel!" Rusty the orange diesel couldn't help laughing at Duncan's story knowing that he had an adventure.
