Senator Tester’s Staff Tours Mountain Line Facility

Tim VanReken, a Legislative Fellow with U.S. Senator Jon Tester’s office, and Jennifer Sweten, Director of Operations at Mountain Line, look at the mechanics of a battery-electric bus in Mountain Line’s maintenance bay.

MISSOULA, Mont.— Mountain Line welcomed Tim VanReken, a Legislative Fellow with U.S. Senator Jon Tester’s Office (D-MT), for a facility tour Thursday. VanReken spent the morning reviewing Mountain Line’s electrification efforts and learning about the agency’s plans to convert to a zero-tailpipe-emissions fleet by 2035.

“We’ve learned a lot in the last three years about charging infrastructure, battery capacity, and the mechanics of maintaining an electric fleet,” said Jennifer Sweten, Director of Operations at Mountain Line. “We’re sharing what we’ve learned with officials and other transit agencies to demonstrate the value of federal support and to help other agencies transition as quickly and efficiently as possible.”

Mountain Line was awarded a $10 million Low or No Emissions grant from the Federal Transit Administration on August 16, which will allow the agency to purchase 10 new battery-electric buses and bring its fleet to 90% electric by the end of the decade. The Low or No Emissions Grant Program received a $1.05 billion increase in funding as a direct result of Tester’s bipartisan Infrastructure Investment and Jobs Act; both Tester and U.S. Senator Steve Daines (R-MT) provided bi-partisan support for Mountain Line’s most recent grant application. Two other Montana agencies also received FTA funding for bus infrastructure improvements.

“Every day, folks in the Treasure State rely on public transit to commute to work, get their kids to school, shop at their local businesses, and enjoy all that Big Sky Country has to offer,” Tester said in an email to Mountain Line staff preceding VanReken’s visit. “This funding for upgrading buses and bus stations across Montana will pay dividends for working families, small businesses, and our climate. I’m proud to have secured cutting-edge investments like this one that will modernize Montana’s transit infrastructure and power our local economies for years to come.”
