The company would work with the community "so that the impact of road traffic is managed appropriately".
Ravensdown has used its rail siding since the 1950s and last year there were 180 rail trips on scheduled trains during spring and autumn.
The final rail trip was last month and the company's shunting locomotive has been sold to a Napier man.
A KiwiRail spokesperson said until recently it carried Ravensdown product to New Plymouth, Wanganui, Utiku and Feilding from Awatoto.
"It was seasonal traffic and we were moving up to seven wagons a day, primarily during spring and autumn, on existing freight services," she said.
"We had also moved product to Gisborne prior to the mothballing of the line between Napier and Gisborne."
There is little chance of the Napier to Palmerston North line being closed due to Napier Port sourcing freight throughout the lower North Island.
"There is still considerable other freight traffic moving between Palmerston North and Napier, so the line will continue to be used and no services cancelled. In particular forestry volumes moving by rail in the lower North Island are growing and we expect this will fill any gap."
