Key Performance Indicators

Streetcar Mean Distance Between Failures

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

Performance (November 2025):

Streetcar mean distance between failures (MDBF) was 758 in November 2025, 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 starting in September. In the meantime, shuttle vans are servicing all streetcar stops. Streetcar KPIs during the service suspension are based on the shuttle operating statistics.

Note: Due to recent data availability, you may notice changes to MDBF for Streetcar this FY. Data on L-Van incidents became available and are now included in the data for this FY. L-Vans are used to replace Streetcar Trains when needed.
