Union Pacific Railroad announced it has signed a contract with National Railway Equipment Co. to build 60 environmentally responsible low-emission diesel locomotives for use in its Los Angeles Basin rail yards.
The new 2,100-horsepower locomotives are called “Generator-Set,” or “Gen-Set,” switchers. Each locomotive is powered by three 700-horsepower low-emissions U. S. Environmental Protection Agency (EPA) non-road Tier 3-certified diesel engines projected to reduce emissions of both nitrous oxides and particulate matter by up to 80 percent, while using as much as 40 percent less fuel compared to current low-horsepower locomotives. Union Pacific began studies and tests of the proto-type Gen-Set switcher locomotive in 2002.
Union Pacific will receive 30 of the new low-horsepower locomotives in 2006, with the remaining 30 to be delivered in 2007. These new locomotives will be used to serve customers and sort rail cars for outbound trains.
Currently, about 47 percent of Union Pacific’s more than 8,200-unit locomotive fleet is certified under existing EPA Tier 0, Tier 1 or Tier 2 regulations which govern air emissions. That gives Union Pacific the most environmentally friendly locomotive fleet in the nation.
It is anticipated that these locomotives will receive California Air Resources Board (CARB) recognition as Ultra-Low Emitting Locomotives (ULEL), in addition to exceeding the EPA’s stringent Locomotive Tier 2 standards. These ULELs are a direct result of Union Pacific’s efforts to encourage development of ever-cleaner technology by its locomotive suppliers. The ultra-low emissions of these locomotives will help Union Pacific meet its commitment to CARB to reduce its fleet average nitrous oxide emissions inside the South Coast Nonattainment Area by 2010.
In addition to the emissions reductions that the Gen-Set switchers will achieve in the South Coast, a June 30, 2005, Memorandum of Understanding (MOU) among CARB, Union Pacific and BNSF Railway will further reduce diesel emissions in and around the state’s rail yards.
CARB has estimated the MOU will reduce particulate emissions by approximately 20 percent at rail yards by June 2008 when all the program’s elements are phased in. Union Pacific expects to spend more than $20 million implementing the program.
