Jeremy Horton announces Alpine Train 3D 1.7, an important feature update to his beautifully constructed virtual train set for iOS devices. Alpine Train 3D offers an easy driving interface, pleasing 3D graphics and ethereal moonlight feel. The world of orca island has now been extended through a portal into space giving panoramic views around the solar system. This adds to the sense of drama created by the mountain views, yeti cave, orca cave and aqua park. Alpine Train 3D is $3.99 and can be downloaded from iTunes.
