freight

Overview
The Wabtec Evolution Series ES43BBi heavy-haul locomotive is engineered for 1,000 mm gauge freight lines. Built on a proven Evolution platform, it combines a service‑proven 12‑cylinder GEVO12 engine (4,500 HP) with eight powered axles and an advanced AC traction system with individual axle control to operate reliably in extreme environments and restrictive clearances.

Features

• Designed specifically for 1,000 mm gauge heavy‑haul operations
• 12‑cylinder GEVO12 engine rated 4,500 HP
• Eight powered axles for high tractive effort
• AC traction with individual (single‑axle) control
• Robust articulated trucks for heavy‑duty and sharp‑curve operation
• Redesigned air‑to‑air cooling and additional blowers integrated on traction motors
• Optimized for extreme climates, tight clearances and sharp curves

Customer Value

• Higher horsepower and tractive effort enables replacement of two DC six‑axle locomotives
• Individual‑axle AC control improves haulage capability and reliability
• Low wheel and rail wear in sharp curves and restricted clearances
• EVO technology reduces fuel consumption and emissions, lowers downtime and extends overhaul intervals
• Reduced lifecycle and operational costs with improved availability
