No 8 "Thunder".
History
The locomotive was built at the workshops at Aylsham station in 1996/7 from components manufactured and
supplied by Winson Engineering.
The outline design is based on a 'Vale of Rheidol Railway'
2-6-2 tank engine, with a mechanical chassis similar to
locomotive numbers 6 7, & 9.
It was originally constructed as an oil fired locomotive and first steamed on the 19th December, 1997.
In late 2005 a thorough overhaul began, which also included converting it from oil to coal firing with the loco returning to traffic again in July 2008.
However due to poor steaming characteristics, its cylinder size was reduced and steam passage ways altered in early 2010 to make the loco more efficient on steam demand.
The loco returned to traffic April 2010.
The locomotive is owned by the Bure Valley Railway.
