The 50th episode of Platform Chats marks a milestone as host Walt Bleser sits down with Anamaria Bonilla, former Chief Engineer of the Metropolitan Transportation Authority Metro‑North Railroad, to reflect on a career shaped by AREMA and a shared commitment to doing the work the right way as part of North America's largest transportation network. Bonilla recounts her journey into rail engineering, the challenges of modernizing legacy systems, and the pride she takes in building a strong, principled engineering team prepared for the future. It’s an episode about mentorship, knowledge‑sharing, and the lasting impact one leader can have on people and the profession.
