Webinar - Online
Alicia Tomaszewski – tec@ieee.org
KK Lee

Abstract:  Through advancement in technology, computing and engineering we have witnessed unprecedented evolution in the railway industry during the past 20 years, in particular in the area of railway asset condition monitoring. This webinar will present the story for each of the following most significant developments in the railway industry in recent years:  

-From DC to AC traction drives

-Railway Signaling and Train Control Systems -  extensive use of Communication Based Train Control (CBTC) systems for metros and European Train Control Systems (ETCS) for mainline railways. There has also been a significant trend of adopting Unattended Train Operation (UTO) mode for metros

-Train Control and Management System (TCMS) to improve the performance and reliability of trains

-Shift of suppliers from custom designed trains to standard product platforms for metro trains to reduce cost and production lead time

-Extensive use of regeneration and energy storage devices to significantly improve energy efficiency

The story will cover the origin, drivers, facilitators, challenges and status of each of the most significant developments. Examples will be drawn from major equipment suppliers, railway operators and maintainers, railway projects and the passengers. It will also present a smart sensor-based system for monitoring of mission critical components of the railway which has been deployed in MTR Hong Kong and SMRT Singapore in recent years.

The webinar will be presented by Dr KK Lee, Professor of Transportation Practice in Hong Kong Polytechnic University  who has been with the railway industry for 50+ years.    

Biography:  KK has been working in the railway industry for over 50 years covering rolling stock and fixed infrastructure maintenance, new lines and major asset replacement projects, operations and business development. During the past 5 years KK has been working initially on the Sydney Metro Northwest project and recently on the Sydney Metro City and Southwest project as advisor to MTR Hong Kong. KK and Professor HY Tam’s  research team in the Hong Kong Polytechnic University has also pioneered in the application of Fiber Bragg Grating(FBG) sensors for the continuous condition monitoring of mission critical components of the railway and commercialization of a FBG sensor based system for continuous monitoring of train and track conditions has been ongoing since 5 years ago.
