We have this same train set. The app that goes with it is pretty cool; you can set up a track in real life and then make the same track in the app, and it will follow along, with little mini games at certain spots, etc. The app train and the real life train stay in sync.

Cool. What is the feedback mechanism to keep them in sync?

Bluetooth

Bluetooth

Are there sensors that tell the controller where the train currently is, on the track?

I highly recommend the accompanying youtube demo video [1] - but only if you enjoy a hacker dad singing fausetto to propel his son's toy train faster around the track. [1] https://www.youtube.com/watch?v=t65X-cs55qM

Almost sounds like the Sprach Zarathustra. Almost. https://www.youtube.com/watch?v=Szdziw4tI9o

you forgot the "Also". Not having it is like calling Nietzsche's novel "Spoke Zarathustra".

The train has a sensor (probably a very simple color sensor) on the bottom that can read the little marker pieces that you place on the track to trigger various functionality. It also knows the approximate speed.

It's a relatively inexpensive toy aimed at young children. You shouldn't expect too much from it.

Why do Duplo trains replicate steam engines instead of contemporary railway technology?

They also have one that imitates a diesel loco: https://www.lego.com/en-us/product/cargo-train-10875 but it's out of stock.

The train base is actually the same as the Duplo truck base so you can put a truck body on it if you wanted.

And as to the answer, steam train go Choo Choo.

My bad! Thanks for the correction. Unfortunately, can't edit now.
