THE public transport authority has been given the green light to push ahead with a railyard extension in East Perth over the objections of nearby Tully Road residents.

Locals from the Tully Road Action Group fear the five dead-end tracks will lead to round-the-clock noise and vibrations might damage their homes.

Peter Kroll submitted a 36-signature petition to Perth council, which backed their plight and urged the PTA to choose a new site.

The metropolitan regional authority has overridden those concerns but this week announced the PTA would have to add a wall to halt noise.
