Transport for London introduced more Manual Boarding Ramps (MBRs) on some platforms during the Olympic and Paralympic Games. They enable wheelchair and scooter users to get over the gap between the train and the platform.
Kilburn station borrowed an MBR from nearby Willesden Green station and used it for several months. However, it was suddenly removed because of apparent safety issues.
