Not really a model, but can I ask for a Fallout SWEP?

I’d like the Railway Rifle to be fully ported into Gmod, train whistle and all. If you can make it so the railway spikes stick to walls, bonus points to you.

I think the SWEP part of this request belongs in the Lua scripting subforum. That said, I’m sure someone could port it, assuming it hasn’t already been done somewhere else.
