Stuck with Hackett Season 1 Episode 2 Leaving on a Jet Train

Alone in an abandoned rail yard, Hackett is faced with an enticing challenge...taking the rusted old wreckage around him, and using it as a life-sized train set to build his own working locomotive. But he hits a hurdle when he runs out of the only available gasoline in the yard. Without access to modern fuel...or any help- Hackett turns back time and resorts to Victorian technology. In order to get his train on the tracks, he must wrestle steel parts several times his size, fire up a super-hot invisible hydrogen flame, and resurrect Industrial Revolution-era techniques to turn wood into an explosive gas that will power his personal locomotive.
