A group of families impacted by the Inland Rail are calling for an independent inquiry into its route.

But Mr Coulton said he was confident in the thorough work across the last nine years to identify the corridor.

"If the line is shifted, an equal number of landholders that aren't going to be impacted now would be, and they would be just as upset," he said.

"There's no magical way to move freight without going through land unless you're going to use an aeroplane."

The federal member said he had great sympathy for the affected people.

"Some people are impacted more than others but I am concerned that some have chosen to shut the gate and not community with the ARTC (Australian Rail Track Corporation). I think that is a very poor move," Mr Coulton said. 

"If it was coming through my property I would want to have as much input as I possibly could as to the details of it."

With the steel and earth works underway, Mr Coulton said residents needed to realise the Inland Rail wasn't going to be stopped.
