He will serve as the organisation’s next chair while recruitment is underway to find a permanent chair and to fill other board vacancies.
The news comes in response to the announcement of former chair Phillip Strachan’s resignation.
Transport and Main Roads Minister Mark Bailey said Mr Marchant possessed substantial rail experience matched with considerable knowledge of Queensland Rail’s operations and recent challenges.
Mr Marchant has served on Queensland Rail’s board since 2015 and was recently reappointed to the board for another three years,” Mr Bailey said.
“He received an Order of Australia in 2013 for service to the rail industry and has also occupied leadership roles with the Australian Railway Association and Rail Industry Safety and Standards Board.”
