This project will seek to characterise and document the behaviour of freight braking systems in real world settings. In combination with the other work packages, the outputs of this study will be used to inform the conclusions of the project overall and will provide useful input to other research activities on freight safety. Specifically, the outputs from this work package will support the research in characterising longitudinal compressive forces in freight (T1352), and the investigation into the factors impacting freight braking in low adhesion (T1351). The outputs will be achieved through a variety of static brake tests of real freight trains. The specific objectives of the project will be to: 1.Identify suitable testing parameters or categorisation to prioritise testing and agree a test regime. 2.Understand the performance of different locomotives. 3.Understand how braking behaviour varies with different vehicles, brake setups and components. 4.Understand how brake timing and brake force varies down the length of a long train. 5.Understand how different charging/overcharge procedures influence the behaviour of braking systems. Whilst delivering these objectives will have implications on freight braking and deceleration performance. The primary objective of this work is to support research in the topic of freight safety.
