There's no way to make the train stop. Either leap off before it jumps
the track, or ride it into the water pit. Once in the water, you'll see
three barrels which are tied down. Swim down and open the lock to release
the barrels, which will float up to the surface, forming a makeshift bridge.
Cross the bridge and jump down into the water on the other side. Down
near the floor under the water you'll find an exit which you'll need to
follow. Look for air pockets along the way so you won't drown.
After emerging from the water you'll see another scientist dying in a
creative way. Unfortunately you're going to need to go into that water
too. Climb up to the top floor and talk to the scientist about what
swimming around down there, then go jump into the shark cage and grab the
crossbow. The cage will fall into the water and you'll need to kill the
big monster using either the crossbow or your 9mm pistol, both of which
fire underwater.
Underwater, find the red wheel and spin it to open up a nearby door.
You'll have to open it enough to give you some leeway since the door closes
once you let go of the wheel.
Go down the hallways and along the slippery catwalks. Be careful for
crumbling floors; those fishies in the water look hungry. You can leap
across the gaps in the floor, but just barely.
When you get to the electrified steel-mesh wall, either jump through the
hole, or jump down into the water and swim like hell through the opening
down there.
Climb up the stairs and then get to the opposite side of the engine room
by either pushing the crates over to the broken ladder, or turning on the
pistons and jumping, Mario-like, from piston to piston, being careful not
to get squished.
Find your way into a closet where a scientist open a door for you into a
giant freezer area. Don't bother dawdling -- run as fast as you can,
through the ice and snow, since you'll be taking cold damage all the way.
Take the ladder down and out of the frigid area.
Keep on going up the elevator and listen to the guard's abbreviated
speech. You'll get your first taste of the trained assassins now. They're
small and quick, so be careful. An easy way to deal with them is to set a
tripmine around the corner from where you're hiding, and wait for them to
blow themselves up. Otherwise, burst in there with guns blazing and make
sure all three are dead.
Go up the ramp and spin the wheel to open up the door on the other side
of the warehouse. Go through the door, but don't bother trying to defend
yourself from the pummeling you're about to get.
After the short cutscene, you'll be stuck in a Star Wars-ish trash
compactor which is slowly compacting. Hop up from box to box to make your
way out of the compactor, then go behind the walls of the compactor to
procure a crowbar and then drop down a smashed grate.
