Most adventurous and fearless railway lines in the world
 

There are few railway tracks which gives you dashing journey.I got shocked to know that there is a railway track which is passing very near from active volcano in Japan & it is connecting Takamori to Tateno Station in Minamiaso.There are few world's most terrifying and gusty railway tracks, which gives you goose bumps.
