What is a cog train?

Travel Tips

A cog train is a train that uses a cog wheel to go up mountains. The wheel in on the bottom of the train in the middle, and there is an extra track between the rails. This gives the train extra traction when going up steep hills. It works the same way as a roller coaster going up at the beginning of the ride.

A cog train uses 1869 toothed cog gears, rack rails and tilted boilers. It allows the train to climb very steep terrain. See www.thecog.com this train is in Mt Washington, NH

2 good answers..the one on Mt. Washington is cool. Worth a visit. The one in Manitou Colorado is really nice. The area is gorgeous. Perhaps its because Royal Gorge is nearby.

Asking about Switzerland, you must be thinking about going up Jungfrau, the operation is how the others explained it, this is due to the steepness of the climb. I went up the cog railway to Jungfrau in 2000 on a Contiki tour, we had a blizzard up the top with thigh deep power, it was -4 C but that didn't stop us running amuk in it and havin a ball, there was ice caves with beautiful ice sculptures in a maze of tunnels, and all the facilities you come to expect in such a country as Switzerland.
I recommend warm clothing - hope the weather is better for you! But we didn't mind!!!!
