In addition, the overhead sign shown in Figure 6.7 indicates the location of the accessible door.

... 42 Manual to Improve rail transit Safety at platform/Vehicle and platform/Guideway Interfaces Special Treatments for Curved Platforms There are a number of special treatments for curved platforms including the following: • Static gap fillers • Mechanical platform edge • Under-platform mechanical gap filler Static Gap Fillers Static gap fillers that are used on curved platforms are wider than those used on tangent platforms. The extra wide static gap fillers are used to fill the increased horizontal gap that results from the curved platform and vehicle door locations.

Treatments for Shared Use High Height Platforms The most common types of platform-based treatments for platforms gaps on track that is shared between passenger and freight rail operations include hydraulic gangways, movable platforms, and gauntlet track.

A section of the platform moves horizontally toward the door area to allow passengers to board.
