In accordance with the decision to reconfigure the A-Train formation, the re-phasing of the Aura satellite is progressing as planned. The immediate substantial effect of this maneuver is that the footprint of the MLS retrieved column drifts away from the MODIS/Aqua nadir.

The Afternoon or "A-Train" satellite constellation presently consists of three satellites flying in formation around the globe (NASA's Aqua and Aura satellites and CNES' PARASOL satellite). The CALIPSO and CloudSat satellite missions were inserted in orbit behind Aqua in April 2006. A sixth spacecraft, OCO, is planned for launch in 2008 and will be placed ahead of Aqua.

On a more superficial level, A-Train simply looks better than Railroad Tycoon. You view your geographical area from an oblique angle rather than from the side or directly overhead, giving you a better perspective. A-Train has easily accessible pull-down menus in a frame around the playing field, allowing you to check with your broker about buying stock, build an amusement park, or obtain a satellite view to survey other areas of your burgeoning empire.
