What is a train meme?

As an AI language model, I don't have the ability to browse memes or have any visual content in my database, but I can provide some general information about train memes. Train memes are typically images or videos that satirize a particular aspect of train travel, such as delays, cramped conditions, or the behavior of other passengers. They often use humor, sarcasm, or irony to point out the absurdity of certain situations on a train. Train memes are often shared on social media platforms and are typically part of internet culture.
