The CTA has been testing two models for the past year. Officials said that made the CTA the first major transit agency in the U.S. to incorporate all-electric buses into daily service on several routes across the city. The buses have traveled 25,000 miles so far and were able to go 80 miles on a single battery charge.
Officials said riders will notice a much quieter ride. Electric buses also mean better air quality for everyone.
The CTA plans to buy between 20 and 30 of the buses later this year, using federal grants.
