Bridge strike protection and impact detection

​Protection beam, Countess Street, Brisbane City

Bridge strike protection

A bridge strike (when an over-height vehicle collides with a rail bridge) can be extremely dangerous. It can also cause costly damage to rail infrastructure and frustrating delays for road users and rail customers.
 
In recent years, Queensland Rail has invested $11.6 million to install protection beams on approach to high priority low-clearance rail bridges across South East Queensland. These specially designed protection beams prevent over-height vehicles coming into contact with the bridge and significantly reduce the likelihood of a vehicle rolling should it strike the beam.

Bridge impact detection

Queensland Rail's bridge impact detection system project allows for bridge strikes to be remotely reported back to Queensland Rail via a Structural Monitoring and Alert System (SMAS).

The SMAS provides remote sensing and video monitoring of bridges to allow for immediate assessment of the impact after a vehicle collision. When a bridge collision is detected, Queensland Rail is forced to halt trains running along that line while an inspection occurs to ensure that the track is still safe to run on. The Structural Monitoring and Alert System helps to reduce the time it takes to resume services. 

The SMAS includes sensors mounted on the bridge structure to monitor and measure the force of an impact, along with a CCTV system to allow remote viewing and recording of the incident. Queensland Rail manages all personal information that may be captured via this process in accordance with its obligations under the Information Privacy Act 2009.

Every low clearance rail bridge is fitted with signage on all approaches. It's up to motorists to know their vehicle height, plan their route to avoid low clearance bridges and stay focused on the road.

Motorists who damage rail infrastructure can be fined up to $1,067 and four demerit points. Queensland Rail actively pursues motorists for the cost of repairs which would otherwise be borne by taxpayers. If the matter goes to court, the maximum penalty for causing damage to rail infrastructure is 80 penalty units  ($10,676).
