It’s a big day for Orange Line riders in Medford – the first new trains went into service this morning.

Mass. Governor Charlie Baker, among other officials, was present at Wellington Station to help introduce the six new Orange Line trains that started running today.

The new fleet of trains are sleek and modern looking. The MBTA say they have more spacious interiors, wider doors, more handrails, LED lighting and LCD displays. They also include safety features like audio and visual warnings.

According to a report from the MBTA, the six new trains have been in testing for more than a year. They’ve accumulated more than 3,800 miles and passed 75 different tests.

To put this all into perspective, MTBA Director of Communications Joe Pesaturo, tweeted that some of the current events happening the last time a new orange line train was put into service were as follows:

-Pope John Paul II visited Boston
-The Iran hostage crisis
-Rosie Ruiz who infamously cheated to “win” the Boston marathon

All of those events happened about four decades ago. The MBTA says this is the beginning of rolling out 152 new Orange Line cars. They say when all those cars are fully in-service, it will increase capacity on the line by 30,000 seats every day.
