its fun…loads of fun coz the train loops, zigzags, backtracks during its ascend/descend to/from the end of line 7000+ feet up and taht too at a slow speed and it allows passengers to get off the train look around down the steep mountain and hop back on the train.: here is another clip for u. the operation of this 112+ years old steam engine in itself is quite interesting:
This animated clip gives u fairly good idea from a great vintage point as to what the journey involves, the climb, the landscape, the houses, the road that run parallel, tunnels, viaducts and the famaous GHOOM LOOP which is at a higher level [7, 400 feet] than the destination, the holiday resort city of the indian elite, Darjeeling at 6 800 feet [famous for Darjeeling Tea Plantations…which is so romantic.[/COLOR]
here, two people stand in the front and sprinkle sand on the tracks for a better traction.
along with a tourist narration:
city of Darjeeling traffic alongside the train…Amazing video 
where this BABY steam engine gets its power to climb 7500 feet
