The MBTA is asking passengers to help pick one of three designs for the new Commuter locomotives it is getting.
All three designs feature the classic purple color known to commuters, but each look varies.
Customers can go to the MBTA website for the next two weeks and choose which one they like by taking a poll. The designs are also hanging up at North and South Stations.
The MBTA is waiting for 20 new locomotives to arrive, a $114 million investment that is the first of its kind in over 20 years for the transit authority.
The new fleet of purple-colored diesel-electric passenger trains will operate more efficiently, reduce fuel costs and emissions and improve reliability, according to a spokesperson from the MBTA.
