"Dame Ann" is an 11,700-pound 2-foot gauge 0-4-2 tank engine, built new at the Exmoor Steam Railway in Bratton Fleming, England in 2004 under works number 320.
Her steam trials were completed at the Launceston Steam Railway in Cornwall. After this, she was delivered to the Wales West Light Railway and RV Park in Alabama, United States. "Dame Ann" is based on the Penrhyn Port Class locomotive built by Hunslet Engine Company in the 19th century. At the time of her construction, she was the first Port Class Hunslet engine built in over 83 years.
