Entrapment and extraction of wheelchairs at flange gaps with and without flange gap fillers at pedestrian railway crossings.

Flange gap fillers that reduce the gap to 10 mm or less eliminate entrapment while retaining acceptable ride quality. Filling flange gaps or leaving a residual gap depth of less than 10 mm is the best option to eliminate risk of entrapment and ensure good ride quality for wheelchair users.IMPLICATIONS FOR REHABILITATIONRail crossings flange gaps pose an entrapment hazard for wheelchair usersPartial or complete flange gap fillers may reduce entrapment but require researchRehabilitation professionals need to educate wheelchair users on techniques to cross flange gaps safelyConsumers and health professionals can consult rail operators to partially fill flange gaps.
