LTK-designed railcarStopping corrosion in its tracks. 

Denver RTD is building a 19.2-mile double track extension to an existing light rail transit (LRT) system which will add an additional 13 passenger stations to the system. Corrosion control is an important part of the plan because it is much cheaper to prevent corrosion than to have to perform frequent maintenance on rapidly corroding infrastructure.

LTK’s corrosion control experts provided the full set of corrosion control engineering services from developing design criteria, reviewing cathodic protection design for more than 52 water and 17 sewer pipelines and commenting on electrical isolation requirements in the Trackwork design to designing stray current monitoring and mitigation for a 20 inch, high-pressure gas pipeline crossing the maintenance yard and reviewing the design characteristics for all concrete structures, though auditing all aspects of the project to ensure the contractor is in compliance with their quality and design criteria.

RTD benefits from this early stage planning and engineering from reduced maintenance costs right from the start of the new extension. Good corrosion control built into the system means fewer problems and costs in the future.
