The Dallas-Area Rapid Transit System (DART) has employed its first electric-powered bus, and seven of the Proterra Catalyst 35 zero-emission vehicles coming to DART in 2018 are partially funded by a $7.6 million Low or No Emission Vehicle Deployment Program. The grant also helps fund the infrastructure to charge and maintain them.

The electric buses are slated to be used on the D-Link, a downtown circulator route currently subsidized by DART, city of Dallas and Downtown Dallas, Inc. The buses will join the electric light rail trains as zero-emission vehicles in DART's transit fleet.
