Christopher Morley,
Travels in Philadelphia
(1920)
“ There is the clear mellow clang of the trolley gongs, the musical trill of fast wagon wheels running along the trolley rails, and the rattle of hoofs on the cobbled strip between the metals. Particularly easy to identify is the sound every citizen knows, the rasping, sliding clatter of a wagon turning off the car track so that a trolley can pass it. ”
