Well, even in tram systems, there's some degree of block signaling, even if
it's only where the track you're on crosses another track and otherwise
uses street signals. Likewise, at least in the Portland system, light rail
signals in areas where the trains run on street or on a roadway median have
transit priority signals identical to what is ised for bus rapid transit,
usually with a repeater of the signal for adjacent traffic, since trains
can proceed under specific circumstances without a priority signal being
