If you don't understand the appeal of steam locomotives, it's likely because you've never seen one. TV does not do them justice. They are nothing like the soulless electric Millennium Trains that haul sickly wage slaves over rickety tracks. They are alive. They are beasts. Complex, mechanical titans that huff and roar like dragons. Back in the day, they were marvels of science that ruled the rails ? jolly green giants, with wheels.
