Amtrak started tweeting on Tuesday from @AmtrakNEC.
The first tweet went out early Tuesday afternoon and more will be coming about major service disruptions on the Northeast Corridor. There will also be tweets about stoppage of rail traffic because of equipment problems, severe weather, police activity or other causes.
However, disruptions that affect a single train will not result in a tweet.
Amtrak will review the number of followers and retweets of the messages to determine if the pilot program should be modified, made permanent or expanded to other corridors.
