— With a goal of reducing greenhouse gas emissions 26% by the end of the decade, Union Pacific is working to improve locomotive fuel efficiency, plans to roll out battery-electric locomotives soon, and is exploring alternatives to the diesel-electric. UP plans to introduce battery-electric switching locomotives — first in California and then in yards and local operations across the system — and is working with Wabtec and Progress Rail on road locomotives that will reduce emissions. The locomotive reduced fuel consumption of a conventional locomotive lash-up by 10%, and Wabtec officials believe a production version with more batteries can reduce fuel use by up to 30%.
