It's imposseble to find them!I founded only one lever there,but It done nothing for now,king said that I can fix
next truck with details,but there is no details,realy!I looked with my spirit eye every wall and hall,maybe there's some sekret?

the lever you are looking for is in the cavern with the 2nd exit to the track switch. map it you will be coming back here. there is a broken cart the lever is behing it and not easy to see try several positions around cart. remember how dificuly it is sometimes to foucus on a piece of treasure without changing mposition.
