A team of Gunners will be waiting here, with Commander Kaylor briefing them. Once they are dealt with, head inside the transit center. An injured man named Harvey will be sitting on the ground. He will implore the Sole Survivor to help his family who are captured by raiders. Offering to use a stimpak on him will present multiple red speech checks, which, if passed, will cause him to give up more information. He will give out the password to the terminal. Once power is restored to the monorail, use it to leave the Transit Center and on to Nuka-World. Once the monorail is taken, there is no turning back.
After a brief ride, the pre-recorded tour-guide explanation will be interrupted by Porter Gage, who will tell the Sole Survivor to survive the approaching deathtrap and find him.
The quest can be started prior to level 30, by traveling to the Nuka-World transit center. While the Gunners outside of the terminal are leveled to the player character, Kaylor will still be around level 38 at a minimum and may pose a significant threat. The text that appears when leaving for Nuka-World is different, stating that Nuka-World is recommended for at least level 30 player characters.
