Have you seen this movie??? Help?

ok so about 10 years ago I was up one night and watched some B list movie real late.

for the life of me I cant remember the name and cant find it...

Heres the plot does this ring a bell.

Movie starts out with a group of people, that are extreme thrill seekers, They Like to Break Into Impossible places.

They break into the some place, almost get caught but get away by Jumping off the building with parachutes.

the rest of the movie,is Them being trapped underground and being killed off by creatures and kinda zombies.

The movie ends with one person getting away on a train....but while on the train, Its revealed...He is DEAD, They all are...They all died in the beginning of the movie when jumping off the building when their parachutes didnt open...They are in fact in HELL ...

obliviously some of my details may be off...but overall this overview should be good enough to ring a bell if you've seen the movie and know the name of it

thanks
