Gisborne mayor Meng Foon will use the Official Information Act to request a copy of the report KiwiRail has presented to the Government, which says the Gisborne to Napier railway line is not commercially viable.
Business leaders and mayors from Gisborne south as far as Wairarapa are being rallied to continue to press for the line's repair and retention.
Debate on the commercial viability of the line continues as the Government's final decision on whether it will foot the $4 million bill to fix it becomes increasingly overdue.
The line between Gisborne and Wairoa was closed in March after a storm caused washouts on portions of the track.
KiwiRail says the line is not commercially viable, "to operate today or in the foreseeable future''.
