Amtrak's top official says limited Northeast Corridor service will be restored Monday with full service returning by Tuesday.
President and CEO Joseph Boardman spoke Thursday at the site where a train traveling at more than twice the speed limit flew off the tracks, killing eight people and injuring more than 200.
Boardman also said technology that could have prevented the crash will be installed throughout the Northeast Corridor by the end of the year.
The technology known as positive train control has been installed on much of the corridor but not on the sharp curve in Philadelphia where the train derailed.
Congress had set the end of the year as the deadline for PTC to be installed on all train tracks.
