American here, never once heard this phrase used. Seems kind of dumb to have it, like it doesn't even save time describing the situation and if you're already talking about this then you're past the point of worrying about vulgar language.
Getting (CONSENTUALLY) gangbanged by A LOT of guys, like enough that it starts to involve logistics planning to accommodate that many people being in a single space at one time.
Just explained this to my Irish wife. To "run a train on someone" in American slang would mean having group sex with that person, potentially consecutively.
This is not fringe at all. There's way your a gooner and don't know what this means. People even use the terminology to describe the Sex scene Stephen King randomly put in "IT". It's a gangbang but one at a time.
Although i appreciate you sharing this and that it probably is a video of her hanging out with bad boys, i must admit that i did not watch more than maybe 15 sec of that, combined across a new skips forward.
I hate how the US has sexualized every random word or sentence. I'm here telling my American friend how funny it is that German's call smart phones a "handy", like "haha silly random word that makes sense tho haha :)", but no, ma American bud breaks down laughing imagining German's giving each other hand jobs.
Also the constant stopping during any sentence to go "oh, I know what YOU'RE thinking, get your mind out of the gutter!". No, I don't, and now I have the privilege of trying to remember every single word that wa just said and trying to see what inside there could possibly be a penis. This from of "joke" never fails to annoy the shit out of me. Like please can we just continue, or do you really have to recite this copy pasta while I stare like an absolute dunce at you?
I just had a light bulb moment as to what it is that annoys me about a large portion of US-american men: all the "dudes" temper & behaviour is adolescent - as if they never made it past puberty. Which perfectly fits the sexualized language being funny to those guys.
To be fair it's rather odd they call it that. Germans seem rather strange with English in general.
They go to public viewings to watch on their beamers. Even when no one has died. Lothar Matthäus claims "I'm a German record player". They carry stuff around in their body bags and listen to music from "boxen".
Merkel even told the english press about her shitstorm. Every day there is a cringe moment.
In the US I can comfirm both GE (freight and passenger) and siemens passenger locomotives run Linux. Some passenger trainsets/cars still run embedded XP.
Pretty much all locomotives running out there today have a plethora of computers for managing fuel economy, brakes, and positive train control (rules compliance). Fun fact: the union pacific's 4104 'big boy' steam engine was fitted with wabtec's I-ETMS PTC which is powered by Linux so there's literally a steam powered locomotive running Linux.
