You could install little flaps actuated with hydraulics along the train. This could probably be part of the normal braking system. The amount of drag produced by something like this at 1000kmh would likely be very substantial.

You can't just add things to the outside of a train, as you have a certain "gauge" (Not sure if that's the word for it) on a track/tunnel/etc.

You can when you build new lines for your maglev trains.
