No 9 is an 0-6-0DM diesel locomotive used on the Welsh Highland Railway.
On 29 September 2009, a Baguley 0-6-0DM locomotive arrived at Dinas from the Exmoor Steam Centre in Devon. This is builder's number 2395 of 1953, built for the Drewry Car Co Ltd, for Underhill Day & Co Pty Ltd, for South Johnstone Co-operative Sugar Milling Association Ltd in Queensland, Australia. The locomotive has a Gardner 8LW diesel engine derated to 132hp.
The locomotive was built for 2ft gauge. It was South Johnstone Mill's number 9 and was used for sugar cane haulage in the Innisfail district of far north Queensland for many years. It was purchased by a member of the Lynton & Barnstaple Trust in 2004 and shipped from Australia in 2005. It is believed to have been stored in Essex and in Somerset before being moved to Devon.
Early reports suggested that it would be named Castell Cidwm on the WHR.
The wheelsets were removed in 2010, and wheelsets turned to correct gauge ( 597mm from 610mm). No 9 sat on skids in the fuel road awaiting their return. They arrived back in Dinas in June 2011.
