Corn-Cob was an informal term, promoted by the editors of NZ Railfan magazine, describing a New Zealand railway locomotive livery (resulting from the combination of green and yellow in the colour scheme) found in common usage amongst the railfan community. The livery was introduced on 5 May 2004 when Toll Rail took over the rail system from Tranz Rail and replaced the Bumble-Bee livery.^[1] The livery was replaced by the KiwiRail Phase One livery in July 2008. DX 5379 was the first locomotive to wear the livery.^[2] The livery represents the colours of Toll Rail and the colours of Australia.^[2] When KiwiRail took over the rail system from Toll, the Toll logos on the locomotives were covered or "patched" with the KiwiRail logo.

As of January 2020, one DHs, two DSCs, two DSJs and one TR still operate in this livery.

Variations

Since the introduction of the livery in May 2004, there has only been one variation:

• DXB 5143 received the livery in June 2008, had been repainted with a deeper yellow on the front of the cab, running boards and at each end of the loco, however the cab-sides were repainted in lighter shade of yellow. It also lacked the green stripes and Toll Rail insignia on the nose. This was only short-lived and the loco never operated in the livery.^[3]
• Although not an official variation, DBR 1295 wore the livery without the Toll Rail branding on the short-hood.^[4]
