Remember when the MBTA promised new trains by 2019 and everyone was ready to throw something? Get ready for round two.

The Boston Globe reports new Green Line trains could be creeping and screeching up and down Commonwealth Avenue by 2021, seven years from now. One less than the Red Line and Orange Line train ETA.

Future plans for the Green Line were included in MassDOT’s five-year capital plan, which lays out how officials plan to allocate lump sums of cash, portions of which are scheduled to be put towards new trains and the Green Line Extension project.

Over the next five-years, the Globe’ s Martine Powers writes, “MassDOT officials plan to spend $2.6 million for the planning and design of the trains.” If the 2021 is the goal, more money is necessary.

In the coming years, federal and state transportation officials will be searching for spare change in between the cushions, checking each and every pocket, and cracking the codes of various lockboxes trying to find upwards of $3 billion scheduled to be spent on the T.

More than $25o million could be put towards a Silver Line extension into Chelsea, and the Back Bay-Seaport connector.

The Globe reports the entire capital-plan calls for $12.4 billion in federal and state transportation spending. Over 50 percent of funding set aside will go towards highway projects, in Allston, Canton and Springfield

To strengthen its budget the T is looking for $700 million from public-private partnerships.

Richard Davey, MassDOT’s secretary, said the capital-plan is based on current state funding projections. If, as the Globe notes, “gasoline tax hikes” are repealed next November, plans could be cut back.
