If you're talking about sticking turbines onto the train:
It's possible, but pointless. The turbines would spin due to wind speed generated by the movement of the train, so all the power that is going into the turbines has come from the train in the beginning.
Basically you're using the motor of the train to spin the generator of the turbines. The train has to work harder, and the energy you get from the turbines will be less than the extra energy that's being spent by the train.
If you're talking about sticking wind turbines by the track, to spin by the pressure wave:
That's also possible, but almost as pointless. Turbines by the track would resist air flow, and when the train is travelling it will push a cushion of air in front of it. Something getting into the way of this air cushion, (like turbines) would basically make the air in front of the train denser, and harder to push through.
On top of that, there aren't many places where trains go by all the time, so the turbines wouldn't have much to work with.

How many wind turbines at hunstanton?
There are not any wind turbines in Hunstanton yet. One supermarket has applied to build a small turbine.
Where are all of the turbines?
Turbines range in size from the very small air driven turbines in dentists drills to massive units in power plants. The term includes windmills and jet engines, vacuum cleaners and kids' toys.
What is the necessary of compounding in turbines?
compounding of turbines is necessary to make the turbines practically controllable.If compounding is not done the size of the turbine will be huge.Hence by pressure &velocity compounding the turbine becomes small in size &its velocity is also becomes controllable.
Can wind turbines be 20 feet tall?
If you're asking can they be as small as this, then yes, but they won't generate a lot of electricity. Most turbines are 10 or more times this height.
Are small wind turbines an effective source of wind power?
Small wind turbines are an effective source of wind power, but a single turbine will generate power only when the wind hits it at a specific angle and strength. This is why multiple wind turbines are often used at a single site, to pick up different gusts of wind.
Where did trains come from?
A couple of places - but probably the most significant was mining. The tunnels were as small as possible and the carts needed to be guided ... and "tracks" were cheaper than people. All this back in the 1500's.
Can a sole skate attach to your backpack?
yes. easily. or, if you have a small backpack, there is a little hole on the sole skate so you can attach it to a carabiner.
How do you change the solenoids on a 1999 Ford Escort Sport?
Starter solenoid?? Attach + battery cable to ne large post Attach starter cable to 2nd large post Attach trigger wire to either small post Disregard 2nd small post if any
Is there night train Maastricht to Amsterdam?
There are no internal night trains in the Netherlands, the country is just too small. But there regular day trains form Maastricht to Amsterdam.
What will a virus attach to?
it will attach to a cell in the back of your throat
How much horse power does a industrial turbine engine have?
Industrial turbines have many uses. The primary use of turbines today is Electrical Generation. Small turbines are used to operate pumps, compressors and other machinery, and they are used as propulsion units on most ships. These turbines range in size from 10 hp oil pump drives to 1.5 million horsepower generating units.
When were the first wind turbines set up in the U.S.?
Small wind turbines were set up in rural areas of the Midwest during the early twentieth century, but power from utilities largely displaced them during the 1930s.
