Today marks my last day at ALSTOM. It has been a pleasure and great pride to work in the Riyadh

Metro project for the past 8 years. I would like to thank all of my colleagues for the unceasing

support and the great work. I would like to thank all of my superiors who provided nothing less than

the continued support and gudeance in the System Assurance field: Clive, John, and Gilbert.
