Mobility aid specifications

​Trains, trams, buses and coaches have differently sized doors and spaces for mobility aids. If you use a mobility aid, check that it can fit on public transport before you travel.

If you're choosing a new mobility aid, such as a wheelchair or scooter, it's a good idea to check that it meets the specifications below.

You may be unable to travel if your mobility aid is outside these specifications.
