A cable tray apparatus is provided for a people mover system such as a Sky Train or the like. The cable tray apparatus is made up of a plurality of identical cable trays which are secured together in an end-to-end relationship. The cable trays are selectively laterally horizontally adjustable with respect to one another and are selectively vertically adjustable with respect to one another to correspond to curves in the roadway of the system and to correspond to elevational changes in the roadway of the system. Each of the cable trays includes a cover having an upstanding tactile warning device at the side edges thereof. A light is also associated with each of the tactile warning devices.
