Resident Evil 3 Nemesis (PS1) (Part 14)

So I continue through Raccoon City Hall after defeating Nemesis in the last episode. I feel another earthquake and fall through the ground. When I get back to my feet underground, I'm faced with a new enemy a large worm like creature called the Grave Digger. I keep shooting it with my grenade launcher until it slithers off. I hit two switches it was blocking and a ladder comes down. I climb up and end up by the train station. I place the fuse and add the mixed oil to make the train operational again. It triggers a cutscene with Carlos giving me flame rounds for the grenade launcher. As we start moving we hear something going on in the back. I check it out and it's the Nemesis!! Mikail tries to fight it off but is unsuccessful. I shoot the Nemesis down and Mikail tells me to run while he sacrifices himself by blowing up himself and Nemesis with a grenade. That causes the train's breaks to go out. I chose to jump out of the window. We wreck into the Clock Tower. So once inside I have to fight off another horde of zombies. I find the Clock T. Key behind a picture. I find Carlos inside also and he gives me freeze rounds for the grenade launcher.
