I really like this idea. Quite often I am checking train times, etc, especially at work.

I really dislike the idea of relying on something like AWS to make it work, though. If I invest into an IoT/hardware project, I want it to still be usable in 10 years time, not e-waste due to the random whims of Amazon.

In theory you could query the national rail feeds directly: https://www.nationalrail.co.uk/developers/

I may try it sometime with my ESP8266 watch!

You can ditch the AWS part actually. I was originally planned to query the API directly from the Pico W. However the performance was not good.

You can self host the part that on AWS to anywhere else easily, using Lambda is purely because of the free tier thingy.

Network or compute? I don't quite understand how making AWS a middle-man helps?

Guessing it’s to cache the results so it’s faster to access it later

Yes, it also trims out unused information.
