Remote control over the internet

[TheOwenExpress]

I would like to be able to connect my lego train and control it over the internet. I looked around and found a few choices but I wanted input from someone with more experience than I.

My goal is to have the physical train set up at my house while allowing my nephew to remote control it from across the country. And if anyone can recommend a small webcam to mount ontop, I would be immensely grateful.

Are you talking about the new Powered UP trains? Then yes, it's possible, if you're comfortable with programming.

Using Node.js you could create an HTTP server that serves a web interface your nephew could access in a web browser.

I've created a Node.js library to interface with Powered UP trains - https://github.com/nathankellenicki/node-poweredup

You could then send commands to the train when the web interface is hit.
