Each captain is probably assigned a different posting, District, or part of a Dustrict. The way it's worded sounds like Curnow retired from whichever posting they had assigned him - likely the Tower District - with Alexi being promoted to that post, then after she was assigned a different post, Ramsey was given charge of it.
