Medicine Wheel Production’s SPOKE Gallery (110 K Street, second floor) debuts another exhibition curated by Kathy Bitetti, the gallery’s chief curator. The central theme is artists who live or work along the original Fairmount Indigo commuter train line that once served South Boston. This line now runs from Readville in Hyde Park to South Boston.

“Boston, like a living organism, is always changing and connecting, meeting new challenges,” reads a description of the exhibition on Medicine Wheel Production’s website. “The MBTA’s Fairmount-Indigo commuter rail line, despite the poetic draw of its name, was the least traveled and maintained of all the routes out of and into South Boston. Renewed interest and investment are now revitalizing this line, which connects lively Boston neighborhoods once separated from the whole.”

The opening reception is this Friday, Feb. 12, from 5 to 7 p.m. Kathy will give a gallery talk at 6 p.m. The “On the Line” show is collaboration with UMass Boston’s Trotter Institute.  It will close on April 16. Gallery hours are Wednesday through Friday, noon to 5 p.m., and Saturdays by appointment.
