50015 Valiant & 50008 Thunderer were specially repainted for the January 1991 'Cornish Centurion' railtour, and spent the rest of the year as dedicated railtour locomotives. When they were both withdrawn as surplus to requirements on 24 November 1991, they both naturally entered preservation. For a while they worked together on the East Lancashire Railway, and are seen here passing Burrs on 4 October 1992 with the 15:05 Bury to Rawtenstall service, during the line's Diesel Gala.
