PPROXIMATELY 3000 Fluorescent lights, each
equipped with a 48 inch fluorescent lamp
shed their "daylight" into every nook and corner
without shadow or glare. It is more pleasant,
cooler, easier on the eyes and vastly more effi-
cient than any other light.
Escalators of reversible type are a panacea for
that "tired feeling," they connect the mezzanine
floor and train platform.
Travel in the Chicago Subway is pleasant and com-
fortable, speedy and safe.
