The "official" on the train who "shakes his fist" at Temple for jumping off at Taylor may be the train's conductor, or perhaps a chaperone from the college (36).

At the "confectionery-lunchroom" called the Shack, the "man in a soiled apron" who brings fixings to Gowan may be the owner as well as a waiter and cook (33). Gowan calls him "Cap" (short for captain?), but since he has never been to the Shack before that is obviously a generic name.
