OK, I found out what the problem was. Just for the records (in case someone with the same problem comes here):
I restarted the level. I fought all zombies again until I reached the cave with the two guys hiding in there. The cutscene was played. Now it comes: when the cutscene was over I was standing INSIDE the cave now! In my first post here I found myself standing outside the cave and was locked out. So this was a bug! I could have never solved this level. This is a really annoying bug!
BTW: how to restart a level properly?
The only way I could think of was to start the whole game all over again. Then use a cheat to warp to the subway level. First open the console (TAB key) and enable cheats by typing "sissy". Afterwards type "goto ED_Subway2". You'll be warped to the beginning of the subway level inside the running train, where you have to fight your way to the cockpit to press the emergency brake. The problem is that you are completely out of weapons now. So I had to cheat again to get my equipment back. I typed "supercalifragilisticexpialidocious" to simply get everything. To overcome the time limit which can be a bit annoying I used the "bullet" cheat to slow down the game.
That's it.
