The passage of the train is still a familiar sound and site in Glendale. Those who grew up in Glendale can remember the train coming through to pick up and drop off mail. As the train passed slowly through town, the person in charge of mail on the train would throw out a large bag of mail for the Glendale postmaster to pick up. For outgoing mail, the Glendale postmaster would hang a mailbag known as a "catcher pouch" on a "mail hook", located next to the train tracks, before the train's scheduled arrival. The catcher pouch was grabbed by a catcher mechanism (mechanical arm) as the train passed by. This was known as "mail on the fly" because the train could deliver and receive mail without stopping.
