I don't see how the narrative structure isn't apparent.
The train station is introduced.
People are shown waiting for a train.
The passengers board the train.
The train departs
The film closes with the passengers taking in the scenery, the rest of their journey remaining ambiguous to us.
I'm sorry if you were hoping for dialogue or something clearer, again the aim was to construct a short form film from unplanned shots. It's not meant to be a character piece or a meaningful exchange between passengers, its just meant to be a short film showcasing an event, much like expanding upon the efforts of Louis Le Prince.
I state it as "viral" in that it uses amateur equipment (a cell phone) and style to present a subject. Unfortunately, I couldn't find a website that had a clear definition of what I'm trying to say other than Wikipedia, which I know is often considered unreliable. However, many other sites have taken this definition so I am forced to use it:
With the proliferation of camera phones, many videos are being shot by amateurs on these devices. The availability of cheap video editing and publishing tools allows video shot on mobile phones to be edited and distributed virally both on the web by email or website, and between phones by Bluetooth or MMS. These consumer-shot videos are typically non-commercial videos intended for viewing by friends or family.

The end of the video is a poor editing job that I acknowledge as a stupid mistake showing poor effort. I mean to state that the use of the music is protected under "fair use", not the video itself.
NOTE: The amended video has been uploaded onto YouTube.
