6 - THE TRAIN JOURNEY
- To change the track you'll need to dismount the train and walk over to the track direction changer. This may sound easy but there a quite a few enemies to deal with in this area. Once you have dealt with them you can collect some items from the speeder shed and then change the track, you'll this has happened when the 'rail switch' light turns from red to green presumably meaning go! Once you have done this get back in the train and continue your long journey.
- The train will next stop at a barrier. Usually this barrier would just open after permission is granted but as life if never easy you will have to open it yourself. Get off the train but watch out for the helicopter which fires some quite powerful rounds at you. They are usually quite inaccurate though due to the distance they are being fired so its probably time to get the sniper's rifle out. There are also some policemen around where the train stops, deal with them in the appropriate manner. When the area is cleared, dive into the water on the left of the train and make your way to the window of the power station. The window will crack after a short while which is your cue to smash it open. Enter through this and swim fast to the room beyond this one because you will be running out of air fast!

- Then find some spiral stairs and swim all the way to the top floor, it will be a dry area. Then press the track control switch to open the barrier so you can continue your train journey. The open way out though is back the way you came but be warned, fish now inhabit the waters by which you entered and they're not nice either!

- Around where you killed the helicopter and the policemen there are some crates and ammo. Smash and collect appropriately. Now get back on the train and you will begin the 3rd and final part of the journey. The next time you stop be on the lookout for yet more policemen, zombies and headcrabs in the immediate area.

- Once the area is cleared, you need to push the crate to the smashable window in the train shed but watch out because a window to the right side of you will be smashed open and a policeman will open fire. Return the complement and then get inside the train shed through the window.

- The way forwards in achieved by smashing a box in front of a small opening. Crawl through the opening and you will enter a small office. A zombie-rat will attack but should not pose too much of a problem. When this is over a zombie will smash the bars on the office window and will allow you to get out of it. The area round to the left is full of enemies so it needs clearing of course!
- When it is cleared, there are a number of items in the room - collect them if you need them and then exit through a door at the far side of the room into the next area of the train shed. Smash the crates in this area for some items but watch out for the headcrab and his amazing exploding barrel trick.

- Go up the stairs at the end of this area and continue along the passageway. You will fall through the floor which appears to be unable to support your weight any longer!
