On March 11, train speeds are being increased to up to 79 miles per hour south of White River Junction and up to 59 mph to the north.
The speed increases follow upgrades to the tracks.
The upgrades included improvements to 46 road crossings, but there are still a number of non-gated crossings.
Transportation Agency Rail Director Dan Delabruere says the speed increases mean significantly less time for drivers and pedestrians to react to an approaching train.
He reminded people to stop, look and listen when approaching a rail crossing.
