Conquering the Mountain-A Trainz Short is a Trainz video.
It shows Thomas and the other trains trying to go up the very steep hill, which both Thomas and Gordon fail due to a steep drop called "Dead Man's Drop," which both Thomas and Gordon blast down the hill and derail. Henry, on the other side, gets determined and goes up the hill. Henry almost goes down the hill due to the lack of speed, but Edward goes behind Henry and helps him go up the hill. When Henry and Edward reach Dead Man's Drop, both of the engines slow down, and proceed to go down the hill, which they succeed. Mavis meets them at the bottom, which she smiles. Sir Topham Hatt comes to the site, which by the engine's expressions, he was mad. Edward then took Thomas' coaches, while Thomas helps Henry with his load, which Thomas doesn't like.
