I could not reproduce this on a second run-through
This happened to me aswell once...
I'm experiencing something similar,
I'm restarting a game, and just walking around on the tram looking around, and every time now the tram gets stuck and doesn't move at a certain point. I think it's supposed to move downward at this section. It's just past the room with the big rocket.
Waiting does not seem to help.
Other people are having issues with the tram pausing, so collecting them together.
I am having this problem, too. Ran into the red doors closing problem, tried to start a new game, and ran into this problem. Stuck until this is resolved.
I removed all .HL files from the save game folder, and this problem went away. However, after starting a new game, problem reoccurs until .HL files are removed from save folder. Appears related to other save game issues, where things that have happened after a save game are reflected in a save game. In addition to the tram getting stuck, the voice-over from the tram stops after the first loading screen, the box that the tram slows for in the room with the welding robot is already across the track, the guy on the forklift in the rocket room has already passed, and the door in the floor opening animation in the room the tram gets stuck does not occur; the door is already open.
I can confirm Ground-Zero's findings.
Confirming above, it only occurs if you’ve played through the level onto the next, its saving too much when storing level state.
Remove all the c_.HL_ files, start intro and watch until you see the helicopter. Restart a new game, animations like the crate moving infront of the tram are sat at their end positions but once you round the corner and the next subchapter loads, the cover moves and you can descend ok. Play until you get past the airlock and it changes subchapter again, restart and find you get stuck in the tram at the previous point where you’re meant to descend.
If we're sure it's related to level changes, I reported another similar bug: issue #925
The tram ride issue sounds like one of my bugs in issue #1515 . The other thing I noticed is that the Training Room level can only be played through once because the Jump Pack doesn't reappear on it's stand for subsequent play-throughs. Looks as if the state of the levels is persisting between plays.
Try deleting the *.HL? files from your SAVE/ folder and then trying the level again. The next release will automatically do this for ya.
Nothing extracted yet.
Start a new game in HL1.
In the tram ride, wait until the "subject: Gordon Freeman" text shows up.
Do not move.
Wait for the next blast door. When the tram is supposed to turn right, and the blast door is supposed to open, the tram stops. The tram will not move until you move.
Move a bit, and stay still again. After the tram passes through the door, and the door closes, the tram will stop once again, until you move again.
