Lasers and infrared cameras explore Melbourne's tram network like never before
A tram fitted with infrared cameras, laser scanners and
vibration sensors has been used to undertake the most comprehensive
analysis of Melbourne's tram network infrastructure ever
Over 10 nights in May 2018, the tram captured data on 250km of
double track and overhead wires, which will be used to inform
planned maintenance to help to make the network more reliable.
Two video cameras and two laser scanners were pointed at the
rail, while two video cameras and eight laser scanners were used to
complete a profile of the overhead power wires.
Other measurements included vibrations felt through the wheel
bogies, location and proximity of foliage to tram tracks and
structures as detected by 3D laser scanners, and passenger comfort
monitored by three gyroscopic sensors.
All of the measurements were synchronised using GPS to provide
specific locations for each result.
Yarra Trams will use the data to better target planned
maintenance of tracks, trams and the removal of vegetation where
it's needed most.
The technology is from a German supplier, and is used by public
transport operators around the world to better inform them about
Anthea Antonio, Executive Director, Asset Performance &
Projects said: "Yarra Trams is setting new standards that enable
targeted investment to upgrade trams, tracks and other assets.
"This project means we'll have more data than ever before, which
will be analysed by our asset management teams and result in
recommendations for investment in planned maintenance."
