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

Characteristics
Sold 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.

Weapons using this ammunition

 * The railway rifle is currently the only weapon in Fallout 4 to use this type of ammunition.
 * The utility protectron has nail guns integrated inside one or both of its hands. In combat it uses those nail guns as weapons and fires railway spikes. Upon death, it will often have variable amounts of railway spikes on its remains.
