An illustration from 1984 showing the main features of an orbital railgun for the Strategic Defense Initiative program. While the design looks reasonable enough, almost certainly this is either missing a whole lot of important details or has changed them into unrecognizability. Scale is impossible to determine, but a practical space-based railgun capable of generating the projectile velocities needed (typically 10 km/sec) would have been an impressive structure indeed.
