Key Performance Indicators

Streetcar Mean Distance Between Failures

Definition: Measures the mean distance (total mileage) between mechanical failures reportable to National Transit Database.

Performance (March 2026):

Streetcar mean distance between failures (MDBF) was 4634 in March 2026, which met the target of 2,700 miles or more.

Note: Due to utility repair work along the streetcar alignment, streetcar service was temporarily suspended from September through the beginning of February. During that time, shuttle vans serviced all streetcar stops. Streetcar KPIs during the service suspension are based on the shuttle operating statistics.
