Well,

Probably you have misunderstood 'Repulsion'.

Here magnetic field repels the train in forward direction. Same principle applies for Electromagnetic Launchers like Rail Guns.

Look at the figure in my next post to have a clear concept....

In the above figure, the rectangular thing that you see is a part of trian

A very high current is passed through rails. This creates magnetic field in the region shown in the direction penetrating the plane of the figure.

Now apply right hand screw rule. You will find that the direction of force is along the rails. Thus the force pushes the train in forward direction.

Electromagnetic Launchers work on the same principle.
