Managing bridge strikes from rail to road bridges

Over-dimension vehicles striking rail and road bridges internationally is a daily occurrence with each strike causing delays to customers. These strikes have financial implications, damage vital infrastructure, and in extreme cases, cause loss of life. This paper will look at how Network Rail in the UK and the NZ Transport Agency manage the issue of bridge strikes. On the Network Rail system there are on average 5 bridge strikes daily and 2000 strikes yearly. On average each strike delays trains for 2 hours and costs the UK economy £23 million yearly. In Auckland, New Zealand, Penrose bridge has been struck over 40 times in the past 8 years with one strike alone in 2016 causing 3 hours of delays and cost the economy of Auckland over NZD$6-10 million. Network Rail has developed a process to manage the risk of bridge strikes to try to limit the delays to customers, while keeping the infrastructure safely operational. In the case of Penrose bridge which spans over a motorway accommodating 200,000 vehicles daily, collision protection beams and advanced warning variable message signs (VMS) have been installed to protect the asset and reduce the number of bridge strikes.
