In tunnel and station infrastructure they'd use carrier currents, which is basically using wiring as the antenna to pass the signal through enclosed spaces. Bunch of colleges in the area do this at their dorms with transmitter cables inside the building. Allows the students to listen in their rooms, but it's only good for a couple buildings' radius because the signals have to pass through brick, steel beams, etc. I remember being pissed off that BU's carrier currents were always broken and so slow to get repaired that it was impossible to hear WTBU hardly anywhere on campus (that big radio tower on the top of the COM building is vacant...their student station's all carrier current or--now--online streaming). Not exactly a state-of-the-art system, either...decrepit 1950's cabling from decrepit 1950's transmitters. You could probably wire one of these up in your basement from a spool of cheap cable and $50 of mail-order doodads from an electronic components catalog...some assembly required.

Very low power, and very small antenna, all regulated by the FCC

I was taking photos at Melrose Cedar Park today, and when I was standing next to the hut that houses the controls for the station's countdown signs I could hear a digitized voice coming from inside every so often. I noted that it was transcribing the announcements being shown on the signs.It works fine at Anderson/Woburn.
