Kyle Gradinger joins the Division of Rail and Mass Transportation as the Assistant Division Chief, Network Integration. He is excited to work for a state committed to combating climate change with ambitious goals and effective mechanisms to encourage a greater share of trips by rail, transit, on foot and by bike. 

Kyle comes to Caltrans from the Federal Railroad Administration (FRA), where he led the development of FRA's rail planning framework and provided guidance to grantees on projects ranging from multi-state regional rail plans to National Environmental Policy Act level corridor studies and service development plans. At FRA, he fostered an integrated, network-based planning approach for "high-performance rail" (faster, more frequent, more reliable service).  

Prior to the FRA, Kyle crafted comprehensive land use and transportation plans as an urban planner for a small consulting firm in Philadelphia. He also served as President of the Bicycle Coalition of Greater Philadelphia, working to create a safe and comfortable network for cyclists of all ages and abilities.

Kyle is excited to explore all that California has to offer with his wife, Lauren, and their two young sons, ages 1 and 3. He looks forward to hiking in the Sierra and taking the kids for their first west coast "double-decker" train rides on the Capitol Corridor.
