MBTA spokesman Joe Pesaturo wrote in an e-mail that the person entered the station while construction workers were on the job.
“It wasn’t a ‘break-in,’ ” Pesaturo wrote. “He walked into the station while construction crews were working there.’’
Pesaturo said the person had no right to be in the station, which has been undergoing a massive renovation that is expected to be completed later this month.
“Transit Police are reaching out to the Reddit user to learn more about his recent visit,’’ Pesaturo wrote. “The station is an active construction site, and there is no reason anyone should be entering the enclosed area, which is circled by a security fence, including chained gates.”
The post on Reddit included more than two dozen photos showing the stairwells, tracks, and exterior of the renovated station.
“I managed to sneak into the Government Center construction site without being noticed by the construction workers tonight,” the person who posted the photos wrote on Reddit.
Pesaturo said that Transit Police officers “will be keeping a close eye on the job site at all times.”
Transit officials have not kept the ongoing construction work a secret. The T has posted photos from inside the station nearly every month since 2014.John R. Ellement can be reached at firstname.lastname@example.org. Follow him on Twitter @JREbosglobe.
