The Train in the Vary Dimension (異次元列車 I jigen Ressha) is a strange vehicle that appeared in the TV series, Ultra Q in its final episode. It originates from another dimension where the lives of its people are pleasant. By mysteriously manifesting in Earth's dimension, the train would accept passengers who where looking to escape their tiresome lives.
The Train of the Vary Dimension would transport passengers to a place know as the "Vary Dimension". A Sci-Fi writer, Kenji Tomono, who managed to go to the Vary Dimension through an elevator, described the Vary Dimension as free from the hardships and hassles of everyday life, and the dimension's humans lived a life free of stress. When people who find themselves on the train desire to return to their families before they reach the Vary Dimension, the train's conductor will stop the train and allow them to be dropped off back to Earth, leaving only those who committed to the decision of seeing the dimension for themselves. Those that would rather return to the Train to travel to the Vary Dimension, as well as those who returned to Earth's dimension afterwards, will only be tragically denied, as those who decide to board can only visit its destination once in their life.
