Aldridge delivers signals for Inland Rail project

Aldridge continues to be actively involved with the Inland Rail project connecting Melbourne and Brisbane via regional Victoria, New South Wales and Queensland.

Aldridge Railway Signals supplied mainline and shunting signals as well as level crossing lights and trackside control boxes for the 98.4 kilometre Inland Rail section between Parkes and Narromine in NSW.

It also delivered further mainline signals, shunting signals mounted on prewired articulated posts, for the 176km Narrabri to North Star Phase 1 section of the track. In addition to this, Aldridge supplied level crossing post assemblies and ancillary devices as well as numerous trackside facility items including control boxes.

Aldridge delivers on the Sydney Metro

Prior to supplying mainline signals to Inland Rail, in 2019 Aldridge Railway Signals custom designed and supplied smart running, shunting and buffer stop signals, for the first stage of the North West section of the new Sydney Metro, which runs trains from Chatswood to Cudgeong, the terminating marshalling area that’s 40km away.

The smart shunting signals also display the main route indicator (MRI) dual digit number/letter immediately above the point position indicator (PPI), with the upper MRI and lower PPI being totally separate and electrically isolated signals.

The two-digit route number/letter displayed on the upper is a descriptive number which informs the train driver which destination the points arrangement will take him to. This can be programmed to display any two-digit (alphanumeric) combination and can be programmed from the rail operator’s control centre.

Aldridge Railway Systems managing director David Aldridge said while the above arrangement was specific to the Sydney Metro, it is also available as other variants for other rail operators, with an example being yellow LEDs instead of white ones.

“In 2022 Aldridge supplied further signals for the Sydney Metro South project, which extends the existing North West Metro a further 23km, from Chatswood to Bankstown,” he said.

“The smart running signals are based on a European design which includes a white PPI, indicating Proceed Left, Straight Ahead or Right, plus a red horizontal bar for Stop.”

Aldridge drives export sales

While Aldridge has pioneered many local projects starting with the first LED signals on the Sydney City Circle up to supplying the latest smart signals for the North-West and Southern Sydney Metro system, Aldridge is lesser known in Australia for its export sales success.

Aldridge has already supplied 8000 Australian-made signals and components internationally, for projects such as MNDT Malaysian North Double Track (Ipoh to Padang Besar), which is 329km of double track; SDT Southern Double Track Malaysia (Gemas to Johor Bahru), which is a further 200km of double track; North Eastern (Metro) Line Singapore, Circle Line Singapore, Thompson Line Singapore; Taichung Green Line Taiwan; High Speed Rail Test Track in Singapore; Stage 1 of the Wanda–Zhonghe–Shulin line in Taiwan; double track in Thailand, Purple Line Bangkok, Red Line Bangkok; Jakarta Metro; and not to mention numerous projects in Indonesia, New Zealand and the USA.

Innovation continues

In 2019, Aldridge Intelligent Transport Systems unveiled the first fully operational wireless level crossing.

“Installed at a remote ARTC location in the upper Hunter Valley, it is still operational. Since then, we have installed another three crossings, two in Central Queensland and another west of Wollongong NSW and we’re happy to report that there are other orders pending,” David said.

“The wireless level crossing offers a low-cost alternative to conventional crossings because it runs on low voltage, uses solar power with battery back-up and avoids the high costs associated with cable trenching.”

Aldridge Intelligent Transport Systems, which is a technology innovator, and Aldridge Rail Signals, a signal manufacturer, combine to provide cutting edge signalling solutions whether it’s for high speed, metro, passenger, freight or shunting operations.
