A freight train that derailed near Cuba, Ala., caused some problems Monday but was cleaned up by Tuesday.
The track is completely clear of cars and tests have begun to measure the tracks' integrity.
In fact, according to Norfolk Southern officials, the first train made it along that stretch of track late Tuesday afternoon.
The track, which is owned by Norfolk Southern, is used by many carriers, including Amtrak and CSX.
The accident involved a CSX train, which normally would not use this line. But they have been doing so since Hurricane Katrina severely damaged their own tracks.
Amtrak officials say that service will still be disrupted until Thursday. The crescent line runs from New Orleans to New York, through Cuba and Meridian.
On a typical day between 26 and 30 trains pass along the affected stretch of track. This number is higher than normal because of the addition of the CSX trains. Track speed through that area is 25 miles per hour. About a mile of the track was damaged.
