BOSTON -- MBTA General Manager Beverly Scott announced today that she is resigning as head of the cash-strapped public transportation agency.

Scott said in a letter to MassDOT Board of Directors that she will continue to work with the MBTA for the next 60 days to help the agency "return to normalcy" and solve the problems it is facing from what she described as "unprecedented weather conditions."

The MBTA has been plagued by systemic delays and malfunctioning equipment since Winter Storm Juno blasted the region at the end of January. The problems facing the system have only been compounded by two additional major snow storms.

"It has been an absolute pleasure and honor to serve with and lead this dedicated team of transit professionals and public servants," said Scott in her letter to the board of directors that oversees the MBTA.

"I am stunned by the resignation of Dr. Scott. Be clear, this Board has had no discussions at any time about her tenure as General Manager. We hoped and expected that she would fulfill her three year contract, which ends in December of this year. I want to thank Dr. Scott for her skillful and committed leadership over the last 26 months, and wish her the very best as she moves on to her next challenge. In the coming weeks, I will appoint a sub-committee of the Board to direct a nationwide search for her replacement," said John Jenkins, Chairman of the MassDOT Board of Directors in an emailed statement.
