Once power is on leave the power room and walk down the hallway to the Game Station. Shoot your read hand at the switch above the door to meet Mommy Long Legs. Mommy Long Legs is the central antagonist in Chapter 2. She will challenge you to complete a number of games to earn clues that will allow you to start and use the train in the Game Station. She also takes the Red Hand from you, leaving you with only the Blue Hand to use.
Continue forward after this meeting and use your Blue Hand to pull the lever that opens the door to the Game Station. Enter the Game Station. The Game Station is a large open area that serves as the hub for the chapter. In this room you will find entrances to Musical Memory, Wack-A-Wuggy, and Statues. You will also find a large train, which is our ticket out of the chapter.
