Earlier Locomotive Models
A history of performance
The design and operation of today’s Evolution® Series and AC4400 locomotives reflect GE’s expertise gained through the development of earlier product lines. That includes recent special models for passenger and international applications, the DASH Series of locomotives beginning in the late 1970s and, prior to that, the Universal Series of locomotives introduced in the mid-1950s.
GE GENESIS™ Series Passenger Locomotives
Available as either straight diesel with DC propulsion or dual-mode with AC propulsion, GENESIS locomotives have a high-strength, lightweight design, microprocessor-controlled head end power and electronic fuel injection.
Blue Tiger
Developed jointly by GE - Transportation and Bombardier, the Blue Tiger diesel-electric locomotive has an axle weight of less than 25 metric tonnes. It is available in various horsepower ratings and may use either AC or DC propulsion systems.
GE AC4400
Since its introduction more than a decade ago, GE’s AC4400 locomotive has been proving its reliability and productivity in heavy-haul freight applications. Today, thousands of AC4400 units are operating dependably around the world.
Engine
Powering the locomotive model is GE’s 7FDL™ engine, a medium-speed turbo-diesel engine designed to meet the unique demands of locomotive duty. Electronic fuel injection and split cooling promote fuel savings, reduce emissions and lower maintenance costs.
Traction System
Computer-controlled inverters—one per axle—regulate the AC traction motors. This individual axle control assures maximum tractive effort, independent of wheel diameter variation, offering reliable adhesion in all-weather conditions.
Control Capabilities
Microprocessor controls in the AC4400 integrate a range of operator interfaces for improved productivity.
GE DASH 9
DC powered, microprocessor controlled
Built on the successful design of earlier DASH Series models, the GE DASH 9 DC propulsion locomotive continues to be a popular choice for a number of rail customers, offering asset utilization and life cycle cost advantages over older models.
Engine
Powering the DASH 9 is GE’s 7FDL™, a 16-cylinder, turbocharged engine with proven performance and reliability. Electronic fuel injection and split cooling improve fuel economy, reduce emissions and lower maintenance costs.
Traction System
Equipped with GE's HiAd™ trucks, the DASH 9 combines low-weight transfer characteristics with microprocessor-controlled wheelslip for exceptional locomotive performance.
Control Capabilities
Microprocessor controls link locomotive subsystems, provide quick access to operating data via display screens and support on-board diagnostics.
GE DASH 8
A DC propulsion mainline locomotive, the DASH 8 is powered by the GE 7FDL™ 16- or 12-cylinder, turbocharged engine. Electronic fuel injection packages offer fuel economy as well as reduced emissions and lower maintenance costs.
GE DASH 7
A DC propulsion mainline locomotive, the DASH 7 is powered by the 12-cylinder GE 7FDL turbocharged engine and features a performance-proven traction system and speed-based adhesion control with multi-channel LED annunciator panel.
Universal Series
Powered by the GE 7FDL diesel engine, with DC/DC or AC/DC propulsion systems, the Universal Series locomotive features configurations for various gauges, axle loads and horsepower output.
