Train bogie overhaul workshop capacity is now in place at Tallawong in Western Sydney, giving Sydney Metro a dedicated site for heavy maintenance. The facility is designed to keep metro trains ready for service and create 20 skilled jobs.

Train bogie overhaul workshop supports Sydney Metro

The workshop will mainly support Sydney Metro operations, where 45 trainsets currently run between Tallawong and Sydenham. Some of those units entered service when Metro opened in 2019, and they have already travelled more than 900,000 kilometres.

Half of the fleet is expected to reach 1.2 million kilometres later this year. That mileage gives structured overhaul work a clear role in keeping trainsets within operating standards.

Heavy maintenance at Tallawong

At the Tallawong train maintenance workshop, technicians will carry out full disassembly, inspection and repair of the trainsets. Sydney Metro has also confirmed the Tallawong–Sydenham operating context in its fleet testing update.

The checks will cover key subsystems, including traction motors, gearboxes, braking equipment and wheelsets. Worn parts such as bearings, seals and rubber elements will be replaced before trains undergo testing.

After those checks, the trainsets will return to service. The facility has been built primarily for Sydney Metro heavy maintenance, but it can also handle other compatible rail projects. A Sydney Light Rail brake overhaul project has already been confirmed.
