It took nearly four decades, but a horse has once again attained the honor that some call the most difficult achievement in sports: American Pharoah, after winning the Kentucky Derby and the Preakness Stakes, ran to victory in the Belmont Stakes as well.

He's the first Triple Crown winner since 1978. With his win, a total of 12 horses have now achieved the feat.

American Pharoah took the lead early in the mile-and-a-half long race, with Frosted close on his tail. From there, the colt never gave up the front position.

Amtrak will be restoring rail service between Philadelphia and New York at 5:30 Monday morning, the rail service announced Sunday.

Service between the two cities had been shut down since Tuesday, when train 188 derailed in Philadelphia, killing eight and wounding more than 200.

The affected section of track is part of the Northeast Corridor — the busiest railroad in America.

American Pharoah is the king of the nation's horse races this month: in a driving rain, the Kentucky Derby winner took home top prize at the Preakness Stakes Saturday.

Ridden by Victor Espinoza, he left the other horses at Pimlico Race Course eating his mud; with an unofficial time of 1:58.46, he led by an impressive seven lengths.

If he can win the Belmont Stakes on June 6, he'll be the first Triple Crown winner since 1978.
