How fast is that train supposed to travel?
*******
.....The speed limit is 70 mph just before the curve and 50 mph along the curve itself,
the Federal Railroad Administration said....
More info should be forthcoming as they have found the black box
according to the following article.

An analysis by The Associated Press of surveillance video just before the deadly
crash of an Amtrak train in Philadelphia indicates it was traveling about 107 miles
per hour as it approached a curve where the speed limit was 50 miles per hour.
The video shows the train - which was roughly 662 feet long - passes the camera
in just over five seconds. But AP found that the surveillance video plays
back slightly slower than in real time.
So, adjusting for the slower playback puts the train’s estimated speed at
107 miles per hour. The surveillance camera was located at a site just before
the bend in the tracks.
