Fire crews were called to the former rail line at the end of Commonwealth Road just before noon on Sunday.
They found a pile of rail ties on fire, and flames spreading in the grass.
Several RVs were being stored just across the fence from where the fire was burning, but none of them were damaged.
A Lake Country crews responded to the fire.
They say a fire investigator will be brought to the scene.
Chief Steve Windsor said though the fire may have been lit accidentally, it was human caused.
“This is the first one we’ve had, hopefully it’s the last one,” Windsor said. “If it gets to a more inaccessible area or if we have houses built up above it, it definitely could be a different scenario.”
Windsor said the fire took quite a bit of work to put out and mop up.
He said creosote soaked railway ties don’t catch fire easily, but once they start burning, they burn very hot.
