The present invention relates to a transit boarding platform panel for use along the edge of an existing transit platform adjacent a track. The panel comprises a molded base portion formed from a reinforced composite polymer. The base portion has a top deck and bottom plate, a first side intended to be adjacent a track at an edge of the transit platform, a second side opposite said first side and intended to be adjacent the existing transit platform, first end and second side, and between the top deck and bottom plate a series of internal support members. The top deck, bottom plate, first and second sides, first end, second end and series of internal support members are preferably molded at the same time to form an integral unit. The top deck has a detectable warning surface consisting of raised truncated domes detectable by the visually impaired in accordance with Americans with Disabilities Act (ADA): Accessibility Guidelines for Buildings and Facilities. The first side of the panel has a first vertical wall section extending from the top deck and having a top edge and a base. A horizontal flange having inner and outer edges extends inwardly from the base of the first vertical wall section. A second vertical wall section depends from the inner edge of the flange and connects to an outer edge of the bottom plate of the panel. Apparatus to protect the panel from damage are located along the second vertical wall section.
