Dani is a tank engine who's a part of The Crotoonian Railway Police Department. Her job is to patrol the standard gauge lines of The Crotoonian Railway, looking to apprehend anyone who breaks the law and take them to the Railway Impound Lot, where engines who break the law are kept until released. She has no original voice, as she's an O.C. However, though she's a kind engine, her voice should sound like an officer of the law.
