infrastructure integrity

Since 1972, Herzog has demonstrated its commitment to quality and pride through system reliability and the appearance of the right-of-way, infrastructure, and facilities we maintain. To preserve infrastructure integrity, we take a life-cycle and condition-based maintenance approach.

ROW inspection and analysis

Our rigorous inspection practices and asset management technologies provide comprehensive and timely information on component and system conditions.

Scheduled maintenance

After ROW inspections, Herzog will schedule future maintenance services and develop capital budgets for track-related infrastructure.

Immediate response

If a failure or incident occurs, our field personnel respond immediately to reduce potential impacts on passenger operations, restoring service quickly and effectively.

Herzog’s Transit Asset Management 4 (TAM-4) software helps us to capture data, monitor performance, and make informed decisions on our maintenance activities.
