As an Electrical Engineer, I disagree with your premise that you can magically accelerate something with no consequences. Not only will you have recoil from the projectile being pushed forward as the basic laws dictate, but you'll also also have to deal with the consequences of internal pressure on the rails themselves pushing at one another.
There are three rails, two parallel and the required third rail nestled between the two in an orthogonal configuration, all of which will exhibit recoil.
Stop reading/watching bad science fiction

Stop reading/watching bad science fiction really? lol study up then. the rail guns use the same thing as the bullet trains. the "bullet" more like a bullet shaped piece of metal, is pulled forward "not pushed" by the electro magnets at very high speed with very little effect on the gun. no gun powder to create recoil. so no internal pressure.
Hey look, an easy to ready document:
http://science.howstuffworks.com/rail-gun.htm
"Repulsion: The current in each rail of a rail gun runs in opposite directions. This creates a repulsive force, proportional to the current, that attempts to push the rails apart. Because the currents in a rail gun are so large, the repulsion between the two rails is significant."
"It would be more difficult to engineer small arm rail guns, mainly because of recoil. Recoil, the backward action of a firearm upon discharge, is determined by the momentum of the escaping projectile. Multiplying a projectile's mass by its velocity yields its momentum, which for high-velocity rail gun projectiles would be considerable. A portable rail gun that fires very small bullets may be the solution. A small bullet would limit recoil but still carry enough kinetic energy to inflict serious damage."
