Description Icon Description

The surface can be any colour other than red (which is restricted to the blister surface at controlled crossings), but should provide a good contrast with the surrounding area to assist partially sighted people. It should not be used at on-street LRT platforms where the lozenge-shaped platform edge warning surface should be used. The purpose of this surface is to advise visually impaired people of the edge of all off-street railway platforms.

The blister surface can be read by foot or cane, warning of the approach to a rail platform edge. As the blister pattern is offset it can be used to identify the direction the platform edge is running and the correct direction of travel to access a train.
