How much coal would you think it takes to power the cog-rail train up Mt. Washington, in New Hampshire? 

I've hiked that mountain -- almost to the top. It's a nice mountain, but nowhere near as tall as mountains out west. 

It's 6,288 feet tall. 

I was surprised to hear the answer. It takes a ton of coal to get to the top of Mt. Washington. 2000 pounds. 

Explained in this short video.

Presumably no coal is used on the down trip -- although the idea of an unpowered train coasting down Mt. Washington 
is not entirely reassuring.
