The MBTA is nearly doubling the number of cash machines within its subway stations - and the cash-strapped transit agency will pick up an extra $226,400 a year in the process.

The T’s board of directors yesterday OK’d going ahead with leases with Bank of America, TD Banknorth and Select A Branch Inc., to put a total of 19 ATMs in stations, up from 10 that were previously provided by Citizens Bank under a prior contract.

Bank of America won with a $30,000 bid the right to place just one ATM in the busy Park Street station.
