I never saw trolleybuses until I moved to Vancouver, and here they're all modern and top-of-the-line with digital displays and so on. San Francisco is one of the five other cities in North America that runs a trolleybus system, ant its aren't quite as new; buses such as this one on the 14 Mission route were delivered in the early 1990s and still mount the old-style signs, which I found to be a faintly strange juxtaposition in the modern day. It's just that in my experience, practically everything has gone digital by now.
