Many Traveler teams have a base of operations, or ops for short. It is typically outfitted with computers, engineering equipment, medical equipment, and everything else to satisfy the needs of the team.
The Core Traveler Team's ops is located at 5365 4th Street (4th and Millwood), Seattle, Washington. (S1E03: Aleksander, S1E10: Kathryn) Philip Pearson purchased the property using lottery winnings during his first day in the past. (S1E01: Travelers) Philip also lives at ops during his downtime, and Trevor Holden later moves in with him. (S3E02: Yates) After the Helios-685 incident, Philip also buys a turtle he named Poppy and installs her in a terrarium next to his computers. (S1E07: Protocol 5)
Ops is trashed after the Travelers' tussle with non-Traveler FBI agents investigating their movements; after the affair Philip finds Poppy on the floor, safe but unleashed from her cage. Everything is cleaned up and restored to working order shortly. (S2E02: Protocol 4)
