Train ride with a toddler😬

What would you guys do to keep your toddler busy during a 5 HOUR(😫) train ride? There will be no wifi or service during our ride so. Also not allowed to walk around on the train so, we’ll be in our seats lol.

He has an iPad but I’m afraid he’ll get mad when his YouTube videos won’t load. Doesn’t really pay attention to movies, only Boss Baby lmao. Any activity ideas we can do?🤔 he’s 2
