AMTRAK DOWNEASTER Alerts and Updates
Train Delays due to high heat (85+ degrees Fahrenheit)
Due to the excessive heat, a speed restriction has been placed on the railroad reducing the top speed of the Downeaster to 40 mph from Portland to the NH/MA border.
This reduced speed will cause delays of approximately 45 minutes.
We apologize for any inconvenience this may cause.
South of Haverhill however, the speed limit is open to 60 in some areas, and 50, so some lost time will likely be made up.
Heat delays might potentially go into tomorrow, if the hot weather persists.
