Meet Sean Williams, P.E., PMP

PITTSBURGH – Sean Williams is a train control engineer, a project manager and a Senior Associate with Lea+Elliott. He has worked on a variety of automated transit and rail systems, including major railways such as WMATA Metrorail, Bay Area Rapid Transit, Honolulu Skyline, San Francisco’s Muni Metro, Madrid Metro, and London Underground. Prior to joining Lea+Elliott, Sean’s 15+ years in the transportation industry also included working for three CBTC suppliers (Alstom, Hitachi, and Thales) where he held a variety of roles in technical project management, vital software development and testing and commissioning.

Sean particularly enjoys the variety that his position with Lea+Elliott provides. “ I’ve made multiple trips to Singapore for projects like a vehicle fleet expansion, spent time in Honolulu for site testing of the new Skyline which is the first fully driverless rail system in the United States, performed regular visits to supplier facilities in my hometown of Pittsburgh to witness software testing and audit the progress of vehicles being built in their factory, and contributed to engineering reports on exciting new alternative technologies, ” he says. “My work is never boring because each day is unique and presents new challenges.” In addition to acting as ATC Engineer for several CBTC projects, Sean played an instrumental role in positioning Lea+Elliott as the premiere consulting firm for Platform Screen Door (PSD) retrofit projects in North America. He acts as Project Manager and the lead technical contributor for several of Lea+Elliott’s PSD-related projects including studies and preliminary design for the Toronto Transit Commission, construction management of a PSD pilot program with New York City’s Metropolitan Transportation Authority, and several confidential initiatives. Sean is enthusiastic about the potential impact of PSD retrofit projects. “ Many of North America’s metro systems were designed well over 50 years ago, so it’s great to see that more and more agencies are looking to install modern technology like PSDs and CBTC,” he says. “It’s satisfying to work on these projects, and it feels good to know that I’m helping improve the safety and security of these systems for their daily riders. ” Sean’s interest in transportation started at a very young age. “ I always knew that I wanted to work with transit systems, ” he says. “ My parents would take me to Disney World every year, and they said that I was more interested in riding the Monorail system than the actual rides in the parks. That was one of my inspirations to go for a degree in computer engineering. Now, to have the opportunity to work for a highly regarded firm like Lea+Elliott on cutting edge automated transportation projects all around the world… it’s just a dream come true for me. I’m very proud to work here. ” Outside of the office, Sean spends most of his free time with his 3-year-old daughter Reese, 1-year-old son Pierce, and wife Tesla. He also enjoys golfing, cooking, watch collecting, and attending Penn State University football games to which his family has season tickets. “ My wife and I are also carrying on the family tradition of yearly Disney trips with our kids. Maybe in 30 years or so, they’ll be part of the future generation of Lea+Elliott! ”
