Setting it in concrete

More than 420 of our people worked around the clock over the first 10 days of 2021 to successfully carry out the biggest upgrade to the Sydney Harbour Bridge rail line in its history.

Acting Chief Executive Suzanne Holden said that the once-in-a-generation project saw some of the best engineers in the world design and deliver a concrete deck that will allow trains to run more quietly, smoothly and reliably, providing a better experience for our customers and also neighbouring residents.

“Our Engineering and Maintenance crews and many behind the scenes worked incredibly hard,” said Suzanne. “I’d like to thank our experienced team for completing more than 15,000 work hours delivering this project on time, despite inclement weather including heat, high humidity, electrical storms and torrential downpours.”

In what was our most complicated engineering project ever, Sydney Trains work crews replaced the 555 metres of timber deck supporting the track on the bridge’s northern and southern approaches. In its place, they installed a low maintenance, more robust and longer-lasting concrete composite deck made up of 266 3-tonne concrete panels, which were constructed in Newcastle.

To finish the job, the teams had to put a new concrete panel in place every 15 minutes!

Our customers certainly noticed the efforts of the crews working who were at times faced with difficult weather conditions.

“Went past during that huge storm – fair play, they (the crews) kept working where they had to, and took shelter when there was lighting. Much appreciated by us commuter! Thank you.”

“Kudos to the maintenance crews working there today! Great effort from everyone.”

“Thank you to all of you. For your hard work and for making sure that our tracks are safe and well maintained.”

Major Works led the job, which had been planned for a decade and involved contribution and collaboration by teams from across Sydney Trains, including Planning, Service Experience, Media and Procurement. By working together and in close consultation with Greater Sydney, the groups involved ensured it was done with maximum benefit and as little inconvenience to our customers as possible.

While the majority of the work was completed during the 10-day closure, further work to complete the rest of the deck upgrade will be completed over a series of scheduled weekend maintenance windows.

Well done to everyone involved!
