Try not to be distracted by the falling train car, as it’s only a diversion—two Thuggish Splicers come running from around the far side of the car after it crashes to the floor. Put them down with the Electro Bolt and Rivet Gun and hack the Health Station on the left. Try to stop the needle in the blue zone for a free First Aid Kit. You can also smash the Health Station after hacking it to obtain an additional First Aid Kit.
Scour the left-hand office for items and an Audio Diary, then enter the red-glowing Gate Control Room and flip the switch. You’ll be greeted by a voice and an image on the monitor shortly before several Leadhead Splicers attack. Don’t bother trying to fight them. Although your instincts tell you to use a First Aid Kit, this too is unnecessary. You automatically stay alive long enough for the wooden floor to give out before your protective Big Daddy suit does.
You’ll splash-land in the flooded Maintenance Runoff Pumping Station. Head north past the waterlogged debris and up the stairs. Crouch under the low opening to enter the Administrative Storage Room and continue to the Drafting Room beyond the Vita-Chamber.
