The Mayak Chemical train, otherwise known as the Green Machine, is a train used to carry radiation and harmful chemicals to and from the Mayak Chemical Combine. It is infiltrated by Artemis Fowl II and Holly Short, while they were running from goblins of the B'wa Kell triad in The Arctic Incident. It has a piton cord attached to it, and then tugs free Butler and Julius Root from their icy cage they are trapped in. The heavy doors on the train also slam shut at one point, and sever Captain Short's trigger finger.
