Technical Details


Despite the Arizona Diesel being American and in the United States, she is based on the British Hudswell Clarke 0-6-0 diesel shunter which worked at the Manchester Ship Canal. No. 4002 Arundel Castle, affectionately known as "Billy", is preserved in working order by the East Lancashire Railway Diesel Group. Sister locomotive No. 4001 Alnwick Castle is also preserved as a static non-operational exhibit at the Winfields Store site at Rising Bridge. Frankie is another member of this class.


The Arizona Diesel is painted blue and orange with gold lining.
