Maintaining facility appearance


Routine maintenance along with an effective long-term capital program is essential to the success of any rail operation, especially in demanding operating environments. To preserve equipment value, we take a life-cycle and condition-based maintenance approach.

Inspection & monitoring practices

Our rigorous inspection practices and system health monitoring technologies provide comprehensive and timely information on component and system conditions.

Immediate response

If a failure or incident occurs, our technicians respond immediately to reduce the impact on passenger operations, restoring service quickly and effectively. Operating crews have received extensive training on equipment trouble shooting techniques to ensure a rapid recovery to service.

Maintaining facility appearance

We also believe that the appearance of the equipment and facilities we maintain demonstrates our commitment to quality and pride in our work.
