Railway rifle (Fallout 4)

The railway rifle is a weapon in Fallout 4.

Background
A product of Tinker Tom's engineering, the railways rifle shoots railway spikes at lethal velocities. During development there were issues with its cooling unit, and liquid nitrogen was eventually used to decrease the reload time.

Characteristics
The railway rifle fires railway spikes as projectiles in the same manner as a crossbow or a flechette gun. These are rarely found as ammunition, but are cheap to buy and may be recovered from enemies slain using the weapon. 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.

In addition, a train whistle can be heard when reloading the weapon.

Locations

 * Bedford station: On a train car near a sleeping bag.
 * Old North Church: Underground Undercover quest reward, used by Desdemona, sold by Tinker Tom.
