The Sudrian landscape, So beautiful. . . Ah well it used to be. Due to a collapsed laboratory all hell breakers loose on the island as the common fog becomes hostile.

Sodor is a place of happiness and joy. A place where living engines work. However things go horribly wrong as a disease spreads throughout the island turning people into monsters hungry for flesh.

When Gordon The Big Engine heads out on a stormy afternoon express run, everything goes wrong as he is stuck by lightning and his driver, "Keith" and replacement fireman, "Ted" are transported into another world.

Engines slowly start changing on the North Western Railway in the mid 1980's.
