From boston.com:

The MBTA expects to increase the number of weekday train trips between Boston and Worcester this fall, soon after the state closes on a $50 million deal with railroad company CSX Corp. to buy 21 miles of commuter rail track along the Framingham-Worcester line, officials said.

A total of seven weekday roundtrips are set to be added to the current 13 trips made between Boston and Worcester, according to T spokesman Joe Pesaturo.

The Framingham/Worcester line has experienced many delays over the past month; I’d be interested to see whether improved service is part of the plan.
