No a train does not float in the air, no train does.
Any gas with a density lower than air will float on the air. Here is a list of such gases:AmmoniaMethaneHydrogenHeliumHotter air
Balloons filled with helium float because helium is lighter than the surrounding air, creating a lifting force. This is known as buoyancy. Regular air-filled balloons are denser than the surrounding air and do not float.
There is a train, boat and air port in Memphis many other cities have air and train ports
It is possible because a Chinese train MAGLEV floats above a magnet. How does it do it : it takes a bunch of safety precautions but they made it North and North so the magnets repel each other. For more information email me at Trainboybertron@outlook.com

The float has air in it.
Only in water. The air from your mouth is the same density as the air in the room- they will not float in air.
No there is always a resistive force such as air resistance. The closest frictionless train is the japanese magnetic train which has no friction on the track.
Because it has air in it. Air weighs less than water therefore air floats.
Its called bouyancy...any object that is sealed off against water is bouyant...because air is light that water and as long as that air is trapped inside and not let to escape it will float
Balloons float when they are full of air because the helium or air inside is less dense than the surrounding air, creating buoyancy. When they are deflated, the balloon is denser than the surrounding air, causing it to sink rather than float. This is due to the principle of buoyancy and the difference in density between the balloon and the air.
It will float because water has more density than air and barges have air in them
