For a few years I would wait for a train at a station that had a curve just before the station.

Thanks to the curve, I could see all of the train when it was off in the distance. Off in the distance, the train looked quite short.

I could see how short it looked, every day.

And as it got closer, it seemed to get longer.

And by the time it was right next to me, there on the station platform, I could see... it was really long.

I watched this happen, many, many times... and I am sure, that’s the way it looked.

Absolutely.

Did you change any kind of lens or focal length between the observations? Did you even have a lens? I’m guessing you didn’t, at least not every time, right? 😉

So what did change? The distance between you, the train and the background, as the train moved closer and closer to you.
