The South Eastshield Crossing (SEC) is a track which spans from Newton Town in Trans-Antarctica to South Pole City in Eastshield. The track is run by three railways owned by Antrak: the Acoola Express, the Acoola Regional and the Acoola Commuter. One of them is high speed while the two others are regional and commuter. Several other railways run through this track including the high speed Antarctic Express. A railway called Urbancruise had reserved a spot but bailed out in 2006. The South Eastshield Crossing goes on it's own route before joining the Itinerod Circuit.
