INLAND Rail builder, the Australia Rail Track Corporation, says it has never stated that its flood modelling is flawed.
"ARTC has never stated that the flood modeling is flawed," a statement issued to Queensland Country Life reads.
"The reporting on that matter is incorrect and continues to misrepresent ARTC's position on the matter."
The comments come in the run up to a high level meeting in Sydney late this afternoon (Tuesday), where landholders will demand that the controversial route across the Condamine River floodplain ruled out.
Landholders will also demand that the Inland Rail is not re-routed through the also agriculturally important Felton Valley.
However, ARTC's latest comments appear to fly in the face of statement issued on behalf of Inland Rail chief executive officer Richard Wankmuller on February 11, which says that past experiences in areas across the floodplain were not lining up with flood modeling.
"We have to try figure out why that happened ... was there a piece of machinery that pushed the water differently that the model doesn't account for? Was there an embankment or a levee we didn't know about? Did somebody augment their property and build a temporary dam that we didn't know about?" Mr Wankmuller's February 11 statement reads.
"That's why we talk to people. That's why we have to figure out exactly what was happening.
"We truly have to get this right and the only way to get it right is to talk to people and get the information they have."
Those February 11 comments have been seized upon by landholders as an admission that actual flood levels are inconsistent with ARTC's modeling.
ARTC, which is under increasing pressure over its handling of flood modeling on the Condamine River floodplain, said it was necessary to correct untruths about the Inland Rail project.
"We look forward to this opportunity to demonstrate our commitment to public safety through world-class science and engineering," the statement reads.
ARTC said appropriate action would be taken if field investigations revealed any fatal flaw in regard to public safety.
At this afternoon's meeting affected landholders led by Millmerran Rail Group chairman Wes Judd will demand Nationals leader Michael McCormack and deputy Nationals leader David Littleproud force ARTC to act.
Federal Member for Groom, John McVeigh, Senator Susan McDonald, and Federal Member for Parkes, Mark Coulton, are also expected to attend the meeting.
"Landholders have been telling the ARTC and the Australian Government for years that the route selection was flawed and flooding would be exacerbated if ARTC followed through with its plan," Mr Judd said.
"This meeting is critical. Our lives and our livelihoods are on hold. We want answers, not excuses."
Landholders say new route must be decided: Likely to be either the existing rail corridor to near Warwick and across to Gowrie, or a relatively low impact route across forest country on the western side of the Condamine floodplain.
