Wellington

Wellington station was the fourth station to be opened on the HNE, and it opened in September of 1975. At the same time, the Wellington maintenance yard for Orange Line trains opened, replacing the Sullivan Square and Forest Hills yards. This new maintenance facility had the modern tools available to maintain the old 01100 series and the current Orange Line cars in service. Currently, the yard is being expanded and renovated to serve the newest cars on the Orange Line fleet coming this year.

Wellington is located on the east side of Medford and is Medford's only rapid transit station. Other parts of Medford are served by buses and the Lowell Line at West Medford station.Wellington is another bus hub of the northern Orange Line, but not as large as Sullivan or Malden Center. The station is connected by a skybridge to the Station Landing garage and shopping center, which was built next to the station around 1997. The skybridge used to be a people mover which looked like a horizontal elevator, but was ripped out and replaced with the skybridge around 2006 because the people movers always broke down. The current skybridge sits on the track where the people mover used to be. A video of the former people mover in action can be found here: https://www.youtube.com/watch?v=mT3jQkOvBXE.

The station itself has three tracks and two platforms, like most of the original HNE stations. The test track for the Orange Line ends at this station and the Haverhill Line track takes over where the third track would be after Wellington. Surprisingly, the sign for the second platform entrance from the lobby says it's closed, even though it's not.

The "closed" second platform, even though it's open. Oak Grove had the same sign for its second closed platform before it got replaced with "Do Not Enter" a few years back.

Wellington, when it first opened, was the last station on the Orange Line going north to charge the normal subway fare. Malden Center and Oak Grove, and the other stations, if the extension went to Reading, had a different fare setup, which I'll get into in the next station, Malden Center!
