Chatsworth is an older well-spoken train who generally performs the same tasks as Harrison. Being good mannered and polite is very important to Chatsworth. He is a very proud chugger and is always in tip top condition as he feels it's very important to be looking your best. Always one to offer a few words of advice to the trainee's as he chugs around Chuggington on his important duties, Chatsworth considers himself definitely one of the upper crust of chuggers in Chuggington, but he is not a fool. He is always considerate. He always wants a rest or a nap so he can get tired.
He is based on a Baldwin Sharknose Locomotive, Baldwin RF-16.
