That is to say, the track at the steepest point rises at the rate of 37 feet for every 100 feet it goes forward. The average grade is 25% with the steepest being 37.4%. The model contains about 7,000 parts and took about 150 hours to build.Ī conventional railroad could never get a train and a load of people up Mt. The trestle is 10 feet long and faithfully replicates the 25% average grade. This model, built mostly with Meccano parts made in Liverpool, England, is electrically powered from a hidden outside third rail on the far side. A cog railway has large cogs (gears) underneath the engine which engage a toothed rack strip in the middle of the track, providing the necessary force to propel the train. With a maximum grade of 37% and an average grade of 25%, an ordinary train would not have sufficient traction to climb the steep slope. It is now a National Historic Engineering Landmark.
