The National Railway Museum selected 55 002 "The King's Own Yorkshire Light Infantry" for preservation as part of the National Collection. The Friends of the National Railway Museum sponsored the repaint of 55 002 into original green livery for its last eighteen months in traffic, although it carried its TOPS number rather than D9002. As insurance, in case 55 002 should meet with a mishap during its last months, the withdrawn 55 005 "The Prince of Wales's Own Regiment of Yorkshire" was set aside from breaking up at Doncaster Works until Deltic operation on the main line had concluded.
