Railway rifle (Fallout 4)

The railway rifle is a weapon in Fallout 4.

Characteristics
Returning from Fallout 3, the railway rifle fires railway spikes as projectiles, in the manner of a crossbow or a fletchette gun. These are highly rare as ammunition; however, they are cheap to buy. In exchange, the railway rifle has become enormously more powerful from its last iteration, while retaining its ability to do extreme damage to limbs--sometimes even pinning detached ones to walls.

The railway rifle is most effective in VATS at close to mid ranges, although its range is somewhat increased from its last incarnation and can be greatly increased with modification.
