SINGLE-chimney ‘King’ No. 6023 King Edward II will see its operation restricted to heritage lines for the foreseeable future after the Great Western Society (GWS) put its main line aspirations for the Collett 4-6-0 on hold.
The road to main line certification has not been a smooth one for the Didcot-based ‘King’, and since its return to steam in 2011 No. 6023 has yet to venture onto the main line under its own power.
