Enter the rail car to discover a new foe, the Combine zombie, or, "zombine" as Alyx quips. As zombines are apt to do, one of them blows himself up, opening the glass wall to the right.

Oops. Try to let Alyx go first. Toxic head crabs are at the top of the stairs. They'll bring your health down to 1 immediately, but you'll slowly recover as your suit administers treatment. A supply crate is behind me in this shot.

Half Life 2: Episode One Walkthrough - Half Life-2-Episode-One 129

A zombie wave is headed your way and the barnacles do a great job of thinning out the herd. Shotgun ammo and a medkit are found in the hole in the wall ahead/left.

Note that Alyx is vulnerable during all this. She'll tell you to knock the antlions over with your Gravity Gun so she can get a better shot. Try to keep her safe while you work at moving the cars around.

Half Life 2: Episode One Walkthrough - Half Life-2-Episode-One 149

Turn right from the lift then follow the power line along the left wall to this corner door. A body drops from the ceiling. Use your Gravity Gun to pull the plank off the door then ready your shotgun before opening it.

Half Life 2: Episode One Walkthrough - Half Life-2-Episode-One 150

Half Life 2: Episode One Walkthrough - Half Life-2-Episode-One 151
Half Life 2: Episode One Walkthrough - Half Life-2-Episode-One 151

...the power box for the elevator. Don't activate the panel yet, though. Doing so not only calls the elevator, but also triggers a massive zombie attack.

Half Life 2: Episode One Walkthrough - Half Life-2-Episode-One 152
Half Life 2: Episode One Walkthrough - Half Life-2-Episode-One 152

Instead, start gathering supplies and stockpiling them near the elevator. Don't worry about being too neat -- a single explosion will scatter your supplies about. Everything is about to go kablooey in this shot.

Stay near your cache of supplies then jump into the lift as soon as it arrives. Another medkit is waiting for you inside.
