Section 1: Dr. Kleiner's Lab (d1_trainstation_05)
  • 1 of 13: After Alyx leads you into Dr. Kleiner's lab, just stand and wait or look around at stuff until Barney shows up.
  • 2 of 13: Wait until Barney opens up the little side room where your old HEV suit is stored, then go on in and reclaim it.
  • 3 of 13: Then it's waiting time again until you all go into Dr. Kleiner's secret teleporter lab.
  • 4 of 13: The thing is finally working, and it's how you and Alyx are going to get to Dr. Vance's lab in Black Mesa East (in theory).
  • 5 of 13: Alyx gets up on the platform first, so stand and wait while she gets teleported.
  • 6 of 13: After the problem is fixed, you'll be told to flip the activation switch.
  • 7 of 13: It's the little red handle that's at the top of the control box just to the right of the big plugs. (The glass covering over the switch will rise when you're supposed to flip it.)
  • 8 of 13: Alyx will be sent safely to Dr. Vance's lab, and then it's your turn. Get onto the teleportation platform and wait to be teleported.
  • 9 of 13: Drop down off the catwalk and explore around the fenced-off area.
  • 10 of 13: Find one of the two narrow door-like openings in the fence and go through it.
  • 11 of 13: Head to the right and all the way back to find an open fence door leading to some stairs.
  • 12 of 13: TIP: Before you leave this area, you can get two armor batteries if you have the patience.
  • 13 of 13: Soon after you go through a door at the top of the stairs, it'll close and lock behind you and you'll start Section 2: Crossing the Train Yard.
