Typically around 0.6m (2 feet) for standard gauge track.
Those are called sleepers. They spread the weight of the train and track over a wider area, they keep the rails on a set distance from each other, and - since the sleepers are mostly buried - they anchor the track in place on the ground.
In England the cross ties that the track sits on are called "sleepers". In the United States sleepers are cars that the passengers would spend the night on, also referred to as Pullman cars.
wooden sleepers are kept because the weight of train is balanced and distance between tracks same.
The distance between the rail line is one (1) metres apart
Horizontal
The track is bolted into the wood to keep it in gauge. Long rail is very flexible, so a train could easily bend it out of gauge. Concrete sleepers are used too, mostly in Europe though, but they are finding more and more homes in North and South America as time progresses.
A truck drives on the road, and a train is on a train track.
Planks are known as sleepers or ties. They serve two purposes. The first is to distribute the load from heavily loaded wheels on steel rails through to the ballast under the track. The second is to tie the two rails together to stop them from wandering about and being unable to guide the train.

No. Railway tracks are only the rails and ties/sleepers and hardware used to hold the track in place. A railway line is a set of tracks designed to move a train between at least 2 points. A railway line can consist of many tracks.
There is no practical limit to the length of train track. Individual rail sections are welded together to make a continuous track. The longest distance you could currently go on the same train without that train having to leave the tracks would be from Kaliningrad on the Baltic Sea to Vladivostok on the Pacific Ocean.
