Union Pacific Greens Its Refrigerated Boxcar Fleet
Union Pacific Railroad announced last week that its entire fleet of 4,950 refrigerated rail cars is now compliant with the California Air Resources Board (CARB) standards that take effect July 17. The company has invested approximately $18 million in its environmentally-friendly refrigerated boxcars over the past two years. That investment includes installing new Tier IVi diesel refrigeration units on more than 700 boxcars, and Union Pacific estimates that these new units will reduce diesel particulate emissions by 50% over previous refrigerated boxcars.
