The railway spike is a type of ammunition in Fallout 4.


This section is transcluded from Railway spike. To change it, please edit the transcluded page.

Repurposed fastening tools from the pre-War railway system, these spikes are capable of crippling and delimbing those unlucky enough to be the target of their fire. Their speed and kinetic energy are well into the lethal range, and their velocity has been fine-tuned to maximize effectiveness.[1]


Solid iron spikes or nails used to secure railroad tracks to the ground. The spikes can be recovered from slain enemies and are capable of pinning limbs to walls.
