While the original Train to Busan movie might be the most well-known of them, there are two other entries in the zombie franchise. Seoul Station is a violent and bleak origin story for the zombies seen in the film, with gorgeous animation that makes its story even more visceral. The other live-action entry in the franchise is 2020's Train to Busan Presents: Peninsula, which does a good job of showing how the world has evolved since the original movie. While I enjoy all three entries, the original's classic status and deep connections between characters are simply unmatched.
