Thank you! I tried to script it so you encounter a train right as you start to get the control in hands but I guess that wasn't really safe as people can just blast past it if they are already too fast.
The music was supposed to guide, but I couldn't make it so that it's louder when the camera faces it so it's also not really clear. If you hear music, look arround and a train is really near. I should have added a smoke system to the train, making it simpler to spot at a distance.
