"The Mt. Tamalpais & Muir Woods Railway used steam engines to transport trainloads of visitors up the mountain, and gravity cars – so called because they used the energy efficient force of gravity – to take the visitors down...At day’s end, the daring would climb aboard the Gravity Car, and the “Gravity Man” would “turn on the gravity”, and down they would coast over 8 1/4 miles, around 281 turns on the mountain’s 7 % grade to the Mill Valley depot or Muir Woods."
