FILE- In this Dec. 8, 2011 file photo, the Amtrak Downeaster travels through Portland, Maine.
Downeaster train service is returning to its pre-pandemic frequency on Monday, with five round trips a day between Brunswick and Boston and the resumption of service to Old Orchard Beach.
And the last train out of Boston will be held for a late departure on nights when there's a Red Sox game or evening event at T-D Garden in Boston.
Maine passenger rail authority chief Patricia Quinn says preliminary data showed ridership at 28 percent of pre-pandemic levels last month.
That was an improvement over March, when ridership was just 19 percent of pre-pandemic levels.
