For me personally, trams are right up there. Aside from the main issue of sharing the roads instead of having a dedicated line, they really make it easy to get from one part of a city to another, especially for wheelchair users. They’re usually as frequent as buses, but much faster. The stations are much more attractive...
Running is an underrated mode of transport. For some reason it’s socially acceptable to exert yourself hard while on a bike, but not running. When combined with public transport it can make all the difference to be able to make a tight transfer by sprinting for it.
