Construction and Maintenance

Metrolink construction and maintenance crews are constantly working throughout the entire Southern California system expanding capacity, upgrading systems and maintaining existing infrastructure to help provide the highest quality of safety and service to our passengers. This work also helps to ensure a safe and smooth flow of freight rail traffic throughout our region.  Here are examples of the type of work we do to maintain our rail system.
