2022 Monash Institute of Railway Technology Annual Lecture in Railway Engineering

The YTP Committee had the pleasure of attending the annual Monash Institute of Railway Technology (IRT) Dr Stephen Marich lecture last week. It was a pleasure to meet up with others in the rail industry and hear from Distinguished Professor Buddhima Indraratna about some of the key geotechnical challenges and considerations in the design of track structures in the Australian #rail network.

It was a fascinating event with some key takeaways from the lecture for us including:

– The effect of train speed on the degradation of track structure – The deviation and deterioration of track substructure material properties during operations from what was designed

– Increased axial loads of heavy haul increasing the fluidisation of mud leading to settlement – mud pumping

– Role of coal on ballast fouling and impeding on track drainage
