Technology

Key features of the Evolution Series Tier 4 Locomotive include :

More than 70 percent reduction in emissions from Tier 3 locomotive technology;

• Advanced air-to-air cooling system for better performance and lower emissions;

• Increased cooling capacity by 25 percent to help eliminate engine deration in high ambient temperatures or during tunnel operation;

• AC individual-axle traction control for greater hauling power along with reduced slippage on startups, grades and suboptimal track conditions;

• Dynamic braking technology to help reduce wheel and brake wear by 20-40 percent; and

• Computer controlled architecture for improved diagnostics and simplified operation.

Tier 4 and the “GE store”

Outside the labs, there are 47,000 other engineers working at GE. The real payoff comes when they pool their expertise, cross business boundaries, and come up with innovative ways to crack tough problems. Inventing a U.S. EPA Tier 4 compliant locomotive was only possible thanks to GE Transportation’s access to the “GE store.”
