DENVER – Mark Clendennen joined HNTB Corporation’s national rail systems team as rail operations planning manager. He is based in the firm’s Denver office and works with clients nationwide.
Clendennen has more than 12 years of experience in the railway industry, focusing on commuter and freight, that encompasses a broad range of expertise in railway operations and system integration. He has managed and provided expertise on a variety of railway projects, including commuter rail startup, grade crossings, quiet zones, stations, vehicle maintenance facilities, railroad company coordination, and construction services. Through his extensive project involvement, he also has experience involving preparation of configuration management plans, software management plans, design criteria and standards, railroad company agreements, public outreach, and community design review processes.

Prior to joining HNTB, Clendennen served as a project manager for a railroad contractor in Denver, where his responsibilities included planning comprehensive maintenance programs to promote safety.

PTC is a train control technology intended to prevent train-to-train collisions, overspeed derailments, incursions into established work zone limits, and the movement of a train through misaligned track switches. In late 2015, Congress extended the deadline for implementation to Dec. 31, 2018. HNTB is providing a range of planning, design, implementation and support activities on PTC projects in an advisory capacity nationally and for transit agencies around the country.
HNTB’s PTC projects include RTD (Denver); Brightline express passenger rail service between Miami and Orlando; Central Florida Rail Corridor/SunRail; New Jersey Transit; and Sound Transit (Seattle) among others. Work being performed includes signal engineering, rail-highway grade crossing systems, communication engineering, safety engineering, quality assurance and project management.
