Electric locomotive ES40ACi

dieselfreight

Overview
Built on a service-proven Evolution Series platform, the ES40ACi is a diesel-electric heavy-haul locomotive optimized for operation in high-temperature and dusty environments. It is designed to meet UIC 3a emissions and can achieve Tier‑3 levels without after‑treatment while delivering high haulage capability and operational efficiency.

Key features

• Single air-conditioned cab
• AC individual-axle traction control (single-axle control)
• 6 powered axles
• 4,200 HP (3,133 kW) gross
• High starting and continuous tractive effort
• Advanced cooling for high ambient/dusty conditions
• Total fuel capacity ~7,350 L (usable ~7,000 L)

Product details
The ES40ACi provides robust haulage performance with optimized fuel consumption and reduced total cost of ownership (TCO). AC individual-axle traction control maximizes hauling capability on substandard track. The locomotive is powered by a GEVO12 engine and benefits from the global operational experience of the Evolution Series platform.
