Forum:Need help with "the pitt"

I only need two more achievements for fallout 3 (ignots and zeta pads) so i started a new game to get them. I went to the train station for the pitt right after i left the vault but couldn't go, how far in the game do i need to go to get to the DLC spots? i already have a playthrough with 300 hours so i am really not trying to "play the game" all over again.
 * You have to find Werhner. You should have the quest for The Pitt in your log, and Werhner isn't be too far away. Be advised, there's some significant danger between you and him, but not significantly more danger than you already faced on the way to the train tunnel. All of the DLCs except Broken Steel can be started fresh out of the Vault, though you'll need a way to get the money for the ticket if you want to visit Point Lookout, and it's a bit too dangerous for a low level, though not impossible. -- 21:33, July 22, 2011 (UTC)
