Grand-daughters running trains

For this first-time event, I decided on a minimalist method of explaining to my granddaughters where to point the remote, and mentioning its speed knob and direction button. Then I handed the remote over.
All went fine, they figured it out. However, I think I need to make more defined pathways to walk upon...

Nice video Cliff!

Too cute: one with pink slippers, other with bare foots. How many trains can you run at one time?

Thanks! Practically speaking, with only 1 remote, only 1 train. I plan on getting another remote though.
