As with other jumps like this, having to land on a moving target makes it very difficult. The train is quite long but it goes at a fair speed so you will need to figure out when to open the chute to glide fast enough to land on the train.

The train will come from a tunnel on the left side and go into another tunnel on the right. You must land on the train before it reaches the second tunnel. There are open cars on the train and you will need to land on one of these to complete the challenge. The train will emerge from the first tunnel about 10 seconds after jumping.

Open the chute after around 3 seconds to give yourself enough height to reach the train. Descend rapidly so you are almost directly above the train when it comes out of the tunnel. Use precision mode at this point to line up perfectly with the train. Slow your descent a bit and release precision mode if the train is moving away from you. Re-enter precision mode just before you land to make sure you land properly.

You can also land on any carriage but it is easier if you hit the lower ones. You need to make sure you aren’t coming in too fast though as you will roll off the edge and fail.
