Question

Why do they put water on Street Car tracks every once in while? Where does the water come from in the tracks?

Answer 1

I have never heard of this being done, but there is a plausible reason for doing so: to decrease the resistance between the tracks and ground, so that the streetcar power can be used more efficiently.

Answer 2

it comes from the car itself,,,,, it is used to cool down the brakes in the wheels..... its just overflow that you see.

Answer 3

my guess would be to wash debris out of the channel next to the track it self to keep the car ON the track and not be derailed by garbage builup
