Size Matters

The Size Matters campaign aims to prevent future rail bridge collisions by encouraging South East Queensland drivers to know the height of their vehicle and load, and to plan their journey ahead.  

The issue 

During the 2019-2020 financial year, Queensland Rail and its customers have been impacted by a significant number of over-height vehicles and loads colliding with low clearance rail bridges. With a total of 68 rail bridge collisions in South East Queensland, the worst hit locations were Muriel Avenue, Rocklea (9); Visentin Road, Morayfield (9); Logan Road, Buranda (7), Oxley Road, Corinda (7) and Dunlop Terrace, Corinda (5).   

A rail bridge collision is not only hazardous to the driver of the vehicle, their passengers and other road users, they can also endanger rail customers if serious damage is caused to rail infrastructure. Apart from the risk to lives, fines of up to $10,676 can apply for damaging infrastructure and ignoring low clearance signage. 

Rail bridge collisions can also cause lengthy delays for road and rail users. During the 2019-2020 financial year, there were 419 trains delayed as a result.  

The campaign 

The campaign message is simple: 'Know your trucking height' and steer clear of rail bridges where your vehicle or load is too high. By understanding the risks and consequences of losing focus, hopefully drivers will become more alert and plan their journey before heading out on the road.  

Launched in August 2020, the Size Matters campaign is appearing on roadside billboards, social media, radio, Spotify and in popular industry publications.
