Since 1871, the distinctive rack-and-pinion grip system on Switzerland's Rigi railway has revolutionized mountain travel. Created by engineer Niklaus Riggenbach to address slippage on steep inclines, this innovation has efficiently ferried tourists to an impressive height of 1,797 meters. With similar railways emerging across Europe, ongoing enhancements like modern electric railcars ensure this historic line remains a vibrant link to the past.
