I have seen a few railway mini guns on here that were just mini guns shooting railway spikes.  So I just nifskoped the two together and put them in the game.  This is my first mod up on the nexus so I figured why not put this on here.  I have uploaded pics of the location of the gun on here.

For those not sure where it's at its located in Greyditch in one of the abandoned buildings.  I have also put the key for the locker on a dead scientist named Dr. Edwards.  He is lying near by the locker, having died before getting to his weapon.  I have upped the damage on this because I am using fwe and mmm.  I also have given it an obj. effect that I think is fitting for a mini gun that shoots railway spikes.
