Depends.
maglev trains run in electricity, and electricity can come from all sorts of sources.
You can get it from hydro Power, nuclear Power, fossil fuels, solar Power etc.
Renewable or not doesn't matter to a maglev train. They can run on anything that can be turned into electricity.
Trains are useful for moving people quickly and safely.Maglev trains use electricity for power. This can come from renewable energy sources, in which case they have no carbon emissions.Maglev trains have no friction with rails and wheels, so they need less energy to run.
Maglev trains do not use gas, so they are good for the environment.
maglev trains can help simply because they don't use gas. They use magnets to keep them in the air and moving. Which means they will be better for the ozone layer. They are also much faster than regular trains.
Electromagnetic Suspension (EMS)
No. There are no solar trains in the world. There are electric trains, some of which run on renewable energy, but there are no solar trains, that is, trains with solar panels that capture and use solar radiation on the run.
This cannot be answered in the way it was asked. Maglev refers to magnetic levitation trains. This is limited to passenger trains. There are many systems in use on a maglev train system, not simply magnetic levitation - the magnetic levitation is in use in other systems, such as manufacturing, and has even been examined as a part of launching space vehicles, but is not referred to as "maglev".
Considering how fast they go, they use very little energy. If this makes people travel by train instead of by plane, that's good for the environment

Maglev (short for magnetic levitation) trains are trains utilizing [electro]magnetism and superconductors to float train cars that would not require the use of traditional rails which are a source of friction in many current generation high-speed railcars.
Nuclear energy and renewable energy are not related. Renewable energy does not use nuclear energy.
