ABSTRACT:
A stationary inclined platform is positioned along the edge of a train platform such that train passengers approach the edge of the train platform will notice the sudden uphill orientation of the warning platform and will realize that they are approaching the train track area. The warning platform includes a nonskid surface and extends into the track area to bring passengers closer to the train doors. The warning platform is particular useful to visually impaired passengers and facilitates wheelchair access to the train.
