Everyone rides trains. Just outside the station at the Umo Works factory village. It was outside a store, unwatched, and it wasn't locked either. The designers of a new Libretto show off their wares. Except for the very top executives who wear black suits, most officials, managers, and engineers wear the company uniform.
Hats are color coded.
There are probably subtle codes on the uniforms too. The new Libretto. I like it a lot. Wish I had one. Alas, I wasn't permitted photographs on the assembly line floor.
