Beautiful, well done. I love that we can now publish short interactive-ish experiments like that on the plain web. Also, I love the little details - the wheels conform to the shape of the track and the pantograph conforms to the shape of the wires above.
Mean rant below:
However, this suffers from terrible hitching and framerate issues. I tried it both in Firefox and Chrome (latest stable release for both), on Windows, on a i7-6700k cpu and nVidia GTX 1080ti gpu. The framerate just isn't stable and there are random hitches of one or two dropped frames. By itself this wouldn't be that big of a problem, but combined with the very contrasting art style (black on full white), it started giving me a headache and making me seriously sick after a short while. Even when not dropping frames, the motion was quite juddery, e.g. I saw the nearby poles jumping from position to position. I won't ask that the authors resolve the frame-rate issues, because I suspect it's an inherent issue to the browsers. Instead I would suggest that motion blur be implemented to hide the harsh frame-to-frame transitions and less contrast be employed between foreground and background (maybe make the background a bright grey rather than 100% full white).
