A Plug-In Heater Helps Norfolk Southern Reduce Emissions and Save Fuel
Figuring out ways to reduce locomotive diesel burn – Norfolk Southern’s main source of greenhouse gas emissions – resulted in a creative “plug-in” solution in 2015. NS calls it the Sleeper. Working with suppliers, NS’ Mechanical Department developed a custom engine heater system that is being installed at rail yards across NS to reduce unnecessary locomotive idling in cold weather.
Because locomotives don’t use antifreeze, they often are kept idling in cold weather to prevent the engines from freezing. The Sleeper eliminates those concerns: A yard locomotive not in use can be plugged in and turned off. Problem solved.
With the Sleeper, NS achieves the “triple bottom line” of sustainability:
People: It enhances air quality in neighborhoods around rail yards.
Planet: It reduces diesel emissions linked to climate change.
Profit: It helps NS’ bottom line by reducing fuel use and operating costs.
