There is no fourth checkpoint. Here’s tips for the different checkpoints
- Wait for the train to pass before jumping down and hiding in the pit. Wait for the train to pass again before jumping out of the pit and onto the pipes above the train track. Go right from there.
- After you traverse the pipes below the track, wait for the train to pass before you jump back out into the tracks. Make a dash to the right from there.
- Continue right and traverse the pipes. If you can’t get over the large hole, try jumping from the small platform or putting your arms on top of the small pipe and swinging to the right below the pipe. When you get to the end, jump into the big pipe.
Hope that helps!
