You are right Sunhuntin, good eye. Then maybe this is a new train for the MAGNETIC LEVITATION Linear liner Superconductivity Series L0 Special Set given that the train that comes with it is recharged through the station. Might explain the higher cost and the fact that they are going to start selling extra magnetic tracks to increase the size of a layout.
