I found this yesterday as a recommended video while watching a video of a Northern Rail Class 323. Looks like it was made by a Brazilian train spotter.

Have you linked to the right video? That seems to be the video of a real train.

Thanks, I corrected the link.

Looks more "General Electric made" than homemade.

Interesting that the motor is powered when running down. Are they dumping any regen power into a load?
