Every now and then I hear a noise that seems to be pretty much random. The only way I can describe it is the sound of a train horn. If you've played this game, then you'd know what I mean.

This is the first Fallout game I've played, so I don't know if sounds usually mean anything. But I have played Skyrim, another Bethesda game, and in that game there were a ton of sounds that at first seemed to be meaningless that I later realised had a connection, like Nirnroots having their own eerie song.

Does the train horn sound mean anything or is it just random?

    Are you playing with any mods? Ive gone through the story twice and can honestly say I have never heard a sound I would call a Train Horn...

    Yeah, I've also played through this game a ton and have no idea what you're talking about.

    Could you perhaps be using the Railway Rifle? I remember it mostly from Fallout 3, but quick googling confirms that it is in New Vegas. IIRC the weapon makes a train sound when you fire it. Also, @CloseVoters, it is very clear what OP is asking. If you feel content that this is unique to OPs game, a simple "there is no repetative railway sound in vanilla new vegas" answers the question.

    @Timelord64 his edit was made via "improve edit" in the suggested edits queue. Minor edits made by 2k+ users are also perfectly acceptable; the problem is more with edits made by sub-2k users. (Granted this is more of an issue on, say, SO than here.) That's part of the reason why 2k+ users have no minimum character count.

Random noises are ambient sound files. You're most likely hearing a 'metal' one; the kind that like to play when you're near those giant power transmission towers. Try listening to the files in these directories:




Are you perhaps talking about the Bad Karma sound?

It's the only sound that I would make sense of sounding like a train horn. Bad karma can only be obtained by doing "bad" things.

From the wiki:

Karma doesn't have as much of an effect on gameplay as in Fallout, Fallout 2 and Fallout 3, since reputation has a more important place.

However, it does still exist and if someone catches you performing an action that causes negative Karma against their faction you will often lose reputation with that faction; for example, stealing something from The Silver Rush where a Van Graff can see you. They may also become openly hostile despite your reputation with them not being lowered enough for you to be considered hated where they will attack you.

  • you are right, its most likely the bad karma sound. It does kinda sound like a train now that I think about it.
