"You know it never fails to amaze me. Every day, I see something new. Today, it's the sight of a floating sack of coal no less."
Top Hat, High Tide

The Coal Yard is where Bigg City Port's coal supply is. It makes an appearance in the episode High Winds, where Zebedee takes a coal barge to Johnny Cuba, which was from here. It appears again in the episode High Tide when Captain Star discussed the importance of coal towards Bigg City's industry.
