At a customer site I was asked if I knew a way of creating a railway track that was flexible. After an internet search I discovered that a HyunWoo Kim had created one using the railing tool. He created a video of the process but there is no written documentation. However he has uploaded the associated files. Below is a link to the video and files, also if you print screen the dialogue boxes it makes it easier to follow when you are creating your own railway tracks. It is most ingenious and flexible, to the point of being able creating sloped tracks.
