Gah! I just remembered Warren Street and Goodge Street.

Which is the only London Underground line which boasts two towns along its'
route where each town has precisely two stations? I believe the answer is
the Piccadilly with Ruislip/Ruislip Manor and Sudbury Hill/Sudbury Town.
The question may need tweaking to make it clearer. I used the word
"precisely" to eliminate the 3 Hounslows but I'm not sure about use of
"town".
