The "Dash 9" is a designation commonly used for locomotives manufactured by General Electric (GE) under their Evolution Series. These locomotives are widely used by various railroad companies around the world. The Dash 9 locomotives, specifically the GE C44-9W, were first produced in the 1990s and have since been used for freight transportation.
Here are some technical specifications for the GE Dash 9 locomotives, specifically the C44-9W model, though it's worth noting that there might be variations in specifications depending on the specific model and the railroad's customizations:
Prime Mover: The GE Dash 9 locomotives are typically equipped with a 7FDL-16 four-stroke diesel engine, which can produce around 4,400 to 4,500 horsepower.
Traction Motors: They usually feature six axle-hung, nose-suspended, self-ventilated GE 752AG or GE 752AH traction motors.
Maximum Speed: These locomotives are capable of reaching a top speed of around 70-75 miles per hour (112-120 kilometers per hour).
Weight: The weight of a Dash 9 locomotive can vary, but they typically weigh between 400,000 to 432,000 pounds (181 to 196 metric tons).
Fuel Capacity: They have a fuel capacity of approximately 4,300 to 4,500 gallons (around 16,277 to 17,034 liters) of diesel fuel.
Length: The length of a Dash 9 locomotive is typically around 73 feet (22.3 meters).
Electrical System: They employ an alternating current (AC) traction system and are often equipped with advanced electronic control systems for improved efficiency and performance.
Brakes: Dash 9 locomotives are equipped with air brakes and dynamic brakes, which help in controlling and slowing down the train when descending gradients.
Axle Configuration: They are typically built with a C-C wheel arrangement, which means they have six axles.
Fuel Efficiency: Dash 9 locomotives are designed to be more fuel-efficient and environmentally friendly compared to earlier locomotive models, thanks to their advanced technology and emissions controls.
