Maglev portal for Pierreren's maglev : you have to join in surveyor the two red arrows at the ends of portal track with invisible tracks (at portal entry with the track you need and at portal end with a small invisible track going to nothing, otherwise it will not work. The end arrow will be visible only in surveyor and will have no function, but the portal runs only if an invisible track is put at its end (because of the maglev structure). The best is to use the portals to make the maglevs to go to one of them and to leave from other portal, or to go back from the same portal, if you want to keep running numbers. A new consist will not have running numbers ! See for more objects http://trainz-fr.blogspot.com
