Track and Structures Rehabilitation Investments

The Metrorail system is a rapid transit system that consists of 118 miles of tracks, 91 stations and over 1,200 railcars. In 2022, Metro will add seven new stations and 12 track miles with the opening of the Silver Line Extension and Potomac Yard Station on the Blue and Yellow lines. This will bring the system to a total of 98 stations and 130 route miles.

Continued tracks and structure investments are required to ensure safe operations and keep these assets in a state of good repair. In Fiscal Year 2023, we're planning to invest $459 million in track and structures. These investments are organized into two subcategories, detailed below.

Track Infrastructure

The safety and reliability of Metro's rail system relies heavily on an effective track infrastructure program. These investments maintain and improve the tracks by replacing deteriorated rail ties, steel rail and other rail components; stabilizing and tamping the track to ensure track alignment; and improving the electrical and signal conductivity of running rail.

Structures

Metro trains operate through deep underground tunnels as well as large above-ground aerial structures, both of which have distinct maintenance needs. Programs include efforts to prevent water leaks in the underground tunnels from deteriorating the rail and electrical system, tunnel ventilation improvements, and rehabilitation to aerial structures and bridges.
