Generating electicity in trains by applying breaks

An idea worth spreading
My idea is to use the motion of the train to generate power.
Generally trains move with uniform high velocities and they stop in particular stations.
The main purpose of break is to stop the train immediately or gradually.
In the case of trains they should stop at particular stations which are known in very advance,so here we can slow down the train gradually.

Now my idea is to install a gas turbine in the front block of train along with compressor,which opposes the motion of train in forward direction.
When the train is accelerating or speeding up, the front box carrying the turbine set-up should be in closed position,
When the train is needed to be slowdown or stopped we should open the door or shutter,of the front box, such that the turbine set-up will come into action creating heavy drag to stop the train.
Now when turbine runs the power can be generated and stored.
This power may not run the train,but to my knowledge it can meet the internal power requirements of the train...

      In case of cars breaks are to be applied frequently.
      we need a locomotive which stops gradually in particular intervals i.e TRAIN
