info player start2
From Quake Wiki
Info_player_start2 is used in Vanilla Quake as the return point from the end of an episode back into the start map area where episode selections are made by the player. It was placed in a location (in front of the Teleport that originated in the skill selection area) that bypassed the skill selection portion of the level. In any case where a player is entering a level named start.bsp (this needs to be tested as the level name might not be a factor) from another level this is where they will be sent to instead of the info_player_start point entity that is also required for any valid Quake map.
All of the other information found in the info_player_start page is applicable to info_player_start2.
