Next generation cast crossings

Next generation cast crossings: Verified by computer modelling and unique physical testing – Hannah Persson, Senior Engineer – Crossing Development, Engineering & Assurance, Progress Rail and VP Scotland, PWI

Lancaster, Barrow and Carlisle Section in-person meeting

Synopsis: Progress Rail manufactures switch and crossing (S&C) layouts for use in domestic and international markets. Crossings are safety-critical components and Hannah’s novel work has considered the design and analysis of them. Through extensive first-of-their-kind practical trials and finite element modelling the research has assessed the crossing design, enabling design modifications to be justified and incorporated into manufactured crossings. This has provided the foundation on which to extend the trials and consider how a crossing is affected, often adversely, by track voiding.

Hannah is a Senior Engineer at Progress Rail and PWI Vice President for Scotland. Her presentation provides an overview of Progress Rail, the fundamentals of how a cast austenitic manganese steel (AMS) crossing is manufactured and the above-mentioned research, which formed the basis of her PhD.

Meeting in-person from 16:00 for a 16:30 start. Transport from station main entrance at 16:00, return 18:00 approximately.
