What is the distance between the two rails?
What is the distance between the two rails? The US Standard railroad gauge (distance between the rails) is 4 feet, 8.5 inches.
Why are railroad tracks 4 feet 8 inches?
WHEN Stephenson was building the Stockton to Darlington railway, he decided on the gauge by measuring the axle width of 100 farm wagons and taking the average, the result being 4ft 8 in. He may have intended to allow local people to use the track to convey goods with their own wagons.

Fact #8: Trains Travel in Both Directions Tracks aren't one way, so even if you've seen a train traveling east, a train could travel west on the very same track.
