The locomotives, built by Progress Rail in Muncie, Ind., are funded through a mix of local and state funds. The F125 features include U.S. Environmental Protection Agency Tier 4-compliant emissions compliance, AC traction systems, an extended range blend and dynamic brakes with head-end power regeneration capabilities, and advanced crash energy management technology.
Metrolink is the only commuter railroad to order the F125 to date.
