Key Performance Indicators

Streetcar Mean Distance Between Failures

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

Performance (February 2026):

Streetcar mean distance between failures (MDBF) was 2047 in February 2026, which did not meet 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.
