There is a big trolley system here, the cables are strung
everywhere, and you don't go 5 minutes without seeing one
pass
by, I think it replaces the bus system we have at home.
On the traffic light post here, the top light is to stop
cars
for pedestrian crossing, the lower one has these small
lighted dots
and apparently is the traffic light system for the trolley's,
so they can share the roads with the cars.
