I think that this could be the DR.Who of cartoon network. Infinity Train has great atmosphere, characters, humor, concept and execution. I do wish Tulip the main character got a little more character development like how she got on the train, if she really wanted to go home or not, and the design of her two robot friends could have been better. But I really like how it focuses more on character development, puzzle solving and world building instead of just humor and character interactions. It gets us invested and wanting to know what happens next. Also Nerd girls are always a plus. It says it's a failed pilot on cartoon network studios wiki page but Lakewood plaza turbo got an app with 3 shorts and currently says possible series on its wiki page and a pilot this good should get more than one chance.
