I now have this funny Märklin Erector Set on my workbench
Fully electric with coil and steel rod - and one
Model railway transformer. 6 to 7 volts are sufficient
for a nice run. Yes, and it's a James Watt-inspired design!
Have fun and something to laugh about, Arnold; D

Thank you for sharing your video. Your model reminds me of my Trix Stabilbaukasten days. Great model you have built there.
