Thanks for posting this.
Although I have to admit I found this just as disappointing as the one about what powers the trains (spoiler: it’s electric!). Lose the cute hand-drawn diagrams and show photos of the actual stuff — inside a TPSS, cab view of the control panel, etc. — and give a few technical details such as the actual voltages involved or what the door control looks like. I don’t mean expand to a one-hour technical overview only of interest to technical people; but talk to an audience that actually cares about the technology and might one day want to learn more.
