"The new system uses magnets with rare earth elements to create a constant repelling force". Sounds like rows of neodymium magnets placed north-north or south-south, repelling each other. Neodymium is a rare earth. However, presumably they will still need electromagnetic forces to drive the train forward, or backward, or to stop it. It will be interesting to see how this works in practice and what the final operating cost will be.
