A BAN on using mobility scooters on the Metro will remain in place for the foreseeable future.
Metro operator Nexus confirmed the decision, which comes after a three-year review into possible alternative arrangements.
The ban was introduced in August 2008 after four accidents in which scooter users fell on to railway lines, on two occasions after crashing through closed train doors.
Nexus announced a voluntary review of its own decision and has since consulted access groups, carried out safety audits and looked at alternative proposals.
Powered and manual wheelchairs are still permitted to travel, as are smaller foldable scooters if carried as luggage.
Bernard Garner, director general of Nexus, said: “The safety of passengers has to come first and I am sorry to say that after an exhaustive review we have been unable to identify how these vehicles could travel safely within the confined spaces of Metro stations and trains.”
