Flinders Street Station’s iconic dome has had its most significant clean since it was built in 1910. It was done as part of a $100 million makeover of the station.

As reported by the ABC more than 10 tonnes of pigeon poo was removed from inside the dome by a specialist company and treated as hazardous waste.

The works on the station – which are expected to be complete by 2019 – will also involve a fresh paint job for its facade. (We had a first look at the new paintwork in July last year.)

Also planned are improvements to pedestrian underpasses, new information boards and upgrades to station entrances. Current platforms and toilet facilities will be renovated and a restoration of the Elizabeth Street clocktower was completed in January.

The station’s old ballroom is receiving treatment too; work is being done to stabilise and waterproof its roof. Many proposals have been made for using the space, from running a craft market there, to turning it into accommodation for the homeless, but there are no definite plans yet.

The ABC reports that the Minister for Major Projects, Jacinta Allan, says the works will improve the station’s functionality and protect its history.
