Y'know I'm a patriot and all, but I wish we didn't spend so much of our national budget on the Meme Force. Let's stop shipping our memes overseas and start meming in our local communities
a. The portal maintains itself via energy supplied remotely by the portal gun or
b. Once created, a portal does not require energy to exist. It's simply an anomaly in space-time. A strange loophole whereby one location is closer to another location that it's supposed to be or
c. The portal runs on chuckle-power generated by Cave Johnson's witticisms
I think the idea that the portal generates infinite energy is too complicating and problematic to be assumed.
This still assumes that the portal is an infinite-energy machine, though, which I think is unwarranted and creates more difficulty than is necessary. I would assume that the portal itself has no properties and does not act on other objects.
I don't think the portal contains anything within itself, though. The portal is a non-entity - it's just that if you pass through the portal, you suddenly find yourself in a different location, as if that location were right next to you. The portal itself has no other properties of its own, I'd think.
I think it has to be A. You figure that if it were B, the people on the track would suddenly be traveling at a high velocity, but the train's velocity wouldn't be impacted at all, since there was no impact between the train and the people. Wouldn't this mean that the portal had created energy, which is impossible?

Wow that sure looks expensive
