Taking public transportation is an easy way to reduce your carbon footprint and help the environment.

Double A Charter Services in Rocky Hill recently purchased a trolley fueled by compressed natural gas to make mass transit even more eco-friendly.

Jim Francis, the town manager of West Hartford, hopes to bring back trolley service to West Hartford center this spring.

A similar trolley was used last year to connect Blue Back Square and the town center.

Double A Charter Services is looking into buying more of the eco-friendly trolleys.
